Fixes ROTPK hash generation for ECDSA encryption ...

Forced hash generation used to always generate hash via RSA encryption.
This patch changes encryption based on ARM_ROTPK_LOCATION.
Also removes setting KEY_ALG based on ARM_ROTPL_LOCATION - there is no
relation between these two.

plat/arm/sgi: introduce number of chips macro ...

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

board/rdn1edge: add support for dual-chip configuration ...

RD-N1-Edge based platforms can operate in dual-chip configuration
wherein two rdn1edge SoCs are connected through a high speed coherent
CCIX link.

This patch adds a function to check if the RD-N1-Edge platform is
operating in multi-chip mode by reading the SID register's NODE_ID
value. If operating in multi-chip mode, initialize GIC-600 multi-chip
operation by overriding the default GICR frames with array of GICR
frames and setting the chip 0 as routing table owner.

The address space of the second RD-N1-Edge chip (chip 1) starts from the
address 4TB. So increase the physical and virtual address space size to
43 bits to accommodate the multi-chip configuration. If the multi-chip
mode configuration is detected, dynamically add mmap entry for the
peripherals memory region of the second RD-N1-Edge SoC. This is required
to let the BL31 platform setup stage to configure the devices in the
second chip.

PLATFORM_CORE_COUNT macro is set to be multiple of CSS_SGI_CHIP_COUNT
and topology changes are added to represent the dual-chip configuration.

In order the build the dual-chip platform, CSS_SGI_CHIP_COUNT macro
should be set to 2:
export CROSS_COMPILE=<path-to-cross-compiler>
make PLAT=rdn1edge CSS_SGI_CHIP_COUNT=2 ARCH=aarch64 all

each to those platform components). Extend the existing SCMI interface
that currently supports only a single SCMI channel to support multiple
SCMI channels.

plat/arm/sgi: add macros for remote chip device region ...

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.
