Due to a bug in the Boot ROM, the USB load API turned out not working
as expected.  It is unfixable because the Boot ROM is hard-wired.

Add work around code in TF to bypass the problematic Boot ROM code.

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.
