Aditya Angadi 60f995fd98 plat/arm/sgi: refactor header file inclusions
Upcoming RD platforms have deviations in various definitions of
platform macros from that of the exisiting platforms. In preparation
for adding support for those upcoming RD platforms, refactor the
header file inclusion to allow newer platforms to use a different
set of platform macros.

Vijayenthiran Subramaniam 2d4b719cc6 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

Vijayenthiran Subramaniam 6daeec7094 plat/arm/sgi: add chip_id and multi_chip_mode to platform variant info
Multi-chip platforms have two or more identical chips connected using a
high speed coherent link. In order to identify such platforms,
add chip_id and multi_chip_mode information in the platform variant
info structure. The values of these two new elements is populated
during boot.

Vijayenthiran Subramaniam c7d4a2178b plat/arm/sgi: move bl31_platform_setup to board file
For SGI-575 and RD platforms, move bl31_platform_setup handler to
individual board files to allow the platforms to perform board specific
bl31 setup.
