This patch provides separation of GICD, GICR accessor
functions and adds new macros for GICv3 registers access
as a preparation for GICv3.1 and GICv4 support.
NOTE: Platforms need to modify to include both
'gicdv3_helpers.c' and 'gicrv3_helpers.c' instead of the
single helper file previously.

This platform supports multiple SoCs. The next SoC will still keep
quite similar architecture, but the memory base will be changed.

The ENABLE_PIE improves the maintainability and usability. You can reuse
a single set of BL images for other SoC/board without re-compiling TF-A
at all. This will also keep the code cleaner because it avoids #ifdef
around various base addresses.

By defining ENABLE_PIE, BL2_AT_EL3, BL31, and BL32 (TSP) are really
position-independent now. You can load them anywhere irrespective of
their link address.

Now that various issues in the PIE support have been fixed,
this platform can enable ENABLE_PIE.

I tested BL2_AT_EL3, BL31, TSP, and all of them worked.

uniphier_scp_is_running() reads the UNIPHIER_STMBE2COM register,
but it does not exist on all SoCs.

Do not call this function if the on-chip SCP is not supported.

The legacy console is gone. Re-add the console support based on the
multi-console framework.

I am still keeping the putc, getc, and flush callbacks in
uniphier_console.S to use plat/common/aarch64/crash_console_helpers.S

The console registration code already relies on that C environment
has been set up. So, I just filled the struct console fields with the
callback pointers, then called console_register() directly. I also
re-implemented the init function in C to improve the readability.

Removing the custom crash console implementation has one disadvantage;
we cannot use the crash console on very early crashes because
crash_console_helpers.S works only after the console is registered.
I can live with this limitation.

Tested on my boards, and confirmed this worked like before.

Allow to handle GZIP-compressed images by giving FIP_GZIP=1 from the
command line.

- Images are GZIP-compressed, then packed into FIP.  If Trusted Board
  Boot is enabled, certificates are generated based on the compressed
  images.

- GZIP decompressor is linked into BL2 to decompress images at
  run-time.

UniPhier platform implements non-TF boot ROM.  Prior to the BL2-AT-EL3
support, BL1 (worked as a pseudo ROM) was needed just for ensuring BL2
is entered at EL1-S.  Now, this platform is able to avoid this waste.

Enable the BL2_AT_EL3 option, and remove BL1.

The warm boot mailbox code is compiled if PROGRAMMABLE_RESET_ADDRESS
is disabled.

The warm boot mailbox is useless for UniPhier SoC family because BL1
is not the first image.  The UniPhier platform implements non-TF ROM,
then BL1 works as a pseudo ROM, so it is never executed in the warm
boot.

The reset vector address is not actually programmable for UniPhier
platform, but it should not hurt to enable PROGRAMMABLE_RESET_ADDRESS
to disable the mailbox and remove pointless plat_get_my_entrypoint.

The `override ERROR_DEPRECATION = 1` setting in uniphier platform
makes deprecation of API difficult. Hence removing the same. This
flag should be specified on the command line if needed.

It is not necessary to read data from stdin.  The input file name

Pre-v8.2 platforms such as the Juno platform does not have
the Scalable Vector Extensions implemented and so the build
option ENABLE_SVE is set to zero.

This has a minor performance improvement with no functional
impact.

Building the UniPhier platform in parallel with TRUSTED_BOARD_BOOT=1
could fail due to non-existing directory.  It might be difficult to
reproduce, but here is an easier way to trigger the problem:

$ make PLAT=uniphier TRUSTED_BOARD_BOOT=1 MBEDTLS_DIR=mbedtls certificates
  OPENSSL build/uniphier/release/rot_key.pem
/bin/sh: 1: cannot create build/uniphier/release/rot_key.pem: Directory nonexistent
make: *** [build/uniphier/release/rot_key.pem] Error 2

The $(ROT_KEY) must depend on $(BUILD_PLAT) so that the build directory
is created before the key.

Uses the xlat tables library's Makefile instead of directly including
the source files in the Uniphier platform port.

In a previous patch, the xlat_ctx_t type has been made public.
This patch now makes the *_ctx() APIs public.

Each API now has a *_ctx() variant. Most of them were already implemented
and this patch just makes them public. However, some of them were missing
so this patch introduces them.

Now that all these APIs are public, there's no good reason for splitting
them accross 2 files (xlat_tables_internal.c and xlat_tables_common.c).
Therefore, this patch moves all code into xlat_tables_internal.c and
removes xlat_tables_common.c. It removes it from the library's makefile
as well.

This last change introduces a compatibility break for platform ports
that specifically include the xlat_tables_common.c file instead of
including the library's Makefile. The UniPhier platform makefile has
been updated to now omit this file from the list of source files.

The prototype of mmap_add_region_ctx() has been slightly changed. The
mmap_region_t passed in argument needs to be constant because it gets
called from map_add(), which receives a constant region. The former
implementation of mmap_add() used to cast the const qualifier away,
which is not a good practice.

Also remove init_xlation_table(), which was a sub-function of
init_xlat_tables(). Now there's just init_xlat_tables() (and
init_xlat_tables_ctx()). Both names were too similar, which was
confusing. Besides, now that all the code is in a single file,
it's no longer needed to have 2 functions for that.

Currently, ROTPK_NOT_DEPLOYED flag is set in plat_get_rotpk_info().
It is up to users how to retrieve ROTPK if the ROT verification is
desired.  This is not nice.

This commit improves plat_get_rotpk_info() implementation and automates
the ROTPK deployment.  UniPhier platform has no ROTPK storage, so it
should be embedded in BL1/BL2, like ARM_ROTPK_LOCATION=devel_rsa case.
This makes sense because UniPhier platform implements its internal ROM
i.e. BL1 is used as updatable pseudo ROM.

Things work like this:

- ROT_KEY (default: $(BUILD_PLAT)/rot_key.pem) is created if missing.
  Users can override ROT_KEY from the command line if they want to
  use a specific ROT key.

- ROTPK_HASH is generated based on ROT_KEY.

- ROTPK_HASH is included by uniphier_rotpk.S and compiled into BL1/BL2.

- ROT_KEY is input to cert_create tool.
