Create a new "memmap" target for the Makefile, which prints a
representation of the memory map for the build. The information are
extracted from the .map files by the "print_memory_map.py" tools.

show_memory is a simple tools that parse the blx.map files and print a
representation of the memory layout for the latest build.
This representation is based on standard symbols present on the map
files as: __TEXT_START/END__, __RODATA_START/END__, __STACKS_START/END__
, etc..

ROMLIB extract functions code from BL images to put them inside ROM.
This has for effect to reduce the size of the BL images.

This patch take this size reduction into consideration to optimize the
memory layout of BL2.
A new "PLAT_ARM_BL2_ROMLIB_OPTIMIZATION" macro is defined and used to
reduce "PLAT_ARM_MAX_BL2_SIZE". This allows to remove the gap between
BL1 and BL2 when ROMLIB is used and provides more room for BL31.

The current memory gain is 0x6000 for fvp and 0x8000 for juno.

Arm's GIC-600 features a Power Register (GICR_PWRR),
which needs to be programmed to enable redistributor
operation. Section 3.6.1 in the GIC-600 TRM describes
the power-up and power-down sequence in pseudo code,
which deviates from the current TF-A implementation
in drivers/arm/gic/v3/gic600.c.
For powering on a redistributor, the pseudo code suggests
to loop over the whole sequence (check for transition,
write request bit) instead of just looping over the
ready bit read as TF-A does in gic600_pwr_on().
This patch fixes GIC-600 power up sequence according
to the TRM.

Previous implementation of timers assumed that clk_div has pretty
representation in MHz (10MHz, 100MHz, etc). Unusual frequencies
(99.99MHz) were causing assertion error and made udelay unusable.

The pre-processor directives make it hard to read the non-TBB version of
this function. Refactor the code to improve readability. No functional
change introduced.

In particular, introduce a new helper function load_image_flush(),
that simply loads an image and flushes it out to main memory. This is
the only thing load_auth_image_internal() needs to do when TBB is
disabled or when authentication is dynamically disabled.

In other cases, we need to recursively authenticate the parent images up
to the root of trust. To make this clearer, this code gets moved to a
TBB-specific helper function called load_auth_image_recursive().

As a result, load_auth_image_internal() now boils down to calling the
right helper function (depending on TBB enablement and dynamic
authentication status).

2. Ask for MCE's acknowledgement for entering system suspend

`unsigned long` should be replaced to
1. `unsigned int` or `unsigned long long` - If fixed,
based on the architecture AArch32 or AArch64
2. `u_register_t` - If it is supposed to be 32-bit
wide in AArch32 and 64-bit wide in AArch64.

Translation descriptors are always 32-bit wide, here
`uint32_t` is used to describe the `exact size` of
translation descriptors instead of `unsigned int` which
guarantees minimum 32-bits

* changes:
  gic/gic600: add support for multichip configuration
  plat/arm/gicv3: add support for probing multiple GIC Redistributor frames

N1SDP supports multichip configuration wherein n1sdp boards are
connected over high speed coherent CCIX link, for now only dual-chip
is supported.

Whether or not multiple chips are present is dynamically probed by
SCP firmware and passed on to TF-A, routing table will be set up
only if multiple chips are present.

Initialize GIC-600 multichip operation by overriding the default GICR
frames with array of GICR frames and setting the chip 0 as routing
table owner.
