Add initial support for RD-Edmunds platform. This platform is considered
as a variant of RD-N2 platform with only major change being the CPU
which is Demeter instead of Neoverse-N2.

Add board support for variant 2 of RD-N2 platform which is a four chip
variant with 4 cores on each chip. The "CSS_SGI_PLATFORM_VARIANT" value
is 2 for multi-chip variant. The "CSS_SGI_CHIP_COUNT_MACRO" can be in
the range [1, 4] for multi-chip variant.

A Neoverse reference design platform can have two or more variants that
differ in core count, cluster count or other peripherals. To allow reuse
of platform code across all the variants of a platform, introduce build
option CSS_SGI_PLATFORM_VARIANT for Arm Neoverse reference design
platforms. The range of allowed values for the build option is platform
specific. The recommended range is an interval of non negative integers.
An example usage of the build option is
make PLAT=rdn2 CSS_SGI_PLATFORM_VARIANT=1

AMU counters are used for monitoring the CPU performance. RD-N2 platform
has architected AMU available for each core. Enable the use of AMU by
non-secure OS for supporting the use of counters for processor
performance control (ACPI CPPC).
