On systems that have multiple platform components that can interpret the
SCMI messages, there is a need to support multiple SCMI channels (one
each to those platform components). Extend the existing SCMI interface
that currently supports only a single SCMI channel to support multiple
SCMI channels.

In order to allow the MHUv2 driver to be usable with multiple MHUv2
controllers, use the base address of the controller from the platform
information instead of the MHUV2_BASE_ADDR macro.

For calculating linear core position of CPU cores from slave chips, AFF3
bits has to be used. Update `plat_arm_calc_core_pos` assembly function
to include AFF3 bits in calculation.

Some of the Reference Design platforms like RD-N1-Edge can operate in
multi-chip configuration wherein two or more SoCs are connected through
a high speed coherent CCIX link. For the RD platforms, the remote chip
address space is at the offset of 4TB per chip. In order for the primary
chip to access the device memory region on the remote chip, the required
memory region entries need to be added as mmap entry. This patch adds
macros related to the remote chip device memory region.

Multi-chip platforms have two or more identical chips connected using a

add chip_id and multi_chip_mode information in the platform variant
info structure. The values of these two new elements is populated

RD-E1-Edge platform consists of two clusters with eight CPUs each and
two processing elements (PE) per CPU. Commit a9fbf13e04 (plat/arm/sgi:
move topology information to board folder) defined the RD-E1-Edge
topology tree to have two clusters with eight CPUs each but PE per CPU
entries were not added. This patch fixes the topology tree accordingly.

Introduce macro 'CSS_SGI_CHIP_COUNT' to allow Arm CSS platforms with
multi-chip support to define number of chiplets on the platform. By
default, this flag is set to 1 and does not affect the existing single
chip platforms.
For multi-chip platforms, override the default value of
CSS_SGI_CHIP_COUNT with the number of chiplets supported on the
platform. As an example, the command below sets the number of chiplets
to two on the RD-N1-Edge multi-chip platform:
export CROSS_COMPILE=<path-to-cross-compiler>
make PLAT=rdn1edge CSS_SGI_CHIP_COUNT=2 ARCH=aarch64 all

Enables usage of ARM_ROTPK_LOCATION=regs for FVP board.
Removes hard-coded developer keys. Instead, setting
ARM_ROTPK_LOCATION=devel_* takes keys from default directory.
In case of ROT_KEY specified - generates a new hash and replaces the
original.
Note: Juno board was tested by original feature author and was not tested
for this patch since we don't have access to the private key. Juno
implementation was moved to board-specific file without changing
functionality. It is not known whether byte-swapping is still needed
for this platform.

This patch expands the coding style documentation, splitting it
into two documents: the core style rules and extended guidelines.
Note that it does not redefine or change the coding style (aside
from section 4.6.2) - generally, it is only documenting the
existing style in more detail.
The aim is for the coding style to be more readable and, in turn,
for it to be followed by more people. We can use this as a more
concrete reference when discussing the accepted style with external
contributors.

When Trusted Boot is enabled, images are loaded and authenticated
following up the root of trust. This means that between the initial
console message saying that an image is being loaded, and the final one
where it says that it failed to load it, BL2 may print several messages
about other images on the chain of trust being loaded, thus it is not
always clear which image we failed loading at the end of the day.

The current URL for QEMU_EFI.fd is not found. Update the link to
point to the new one.
If you run the shell command as instructed, you will see this error:
qemu-system-aarch64: keep_bootcon: Could not open 'keep_bootcon': No such file or directory
The part "console=ttyAMA0,38400 keep_bootcon root=/dev/vda2" is the
kernel parameter, so it must be quoted.
As of writing, QEMU v4.2.0 is the latest, but it does not work for
TF-A (It has been fixed in the mainline.) QEMU v4.1.0 works fine.
With those issues addressed, I succeeded in booting the latest kernel.
Tested with QEMU v4.1.0 and Linux 5.5 (defconfig with no modification).
Update the tested versions.
