[edk2-platforms] [PATCH v3 5/5] Platform/ARM/Sgi: Add initial support for RD-N1-Edge-Dual platform

["Vijayenthiran Subramaniam" <vijayenthiran.subramaniam@arm.com>]

For RD-N1-Edge platforms, use multi-chip-mode information from the
SGI platform descriptor HOB to pick the correct ACPI table to be
installed.
