[edk2-platforms][PATCH v4 8/9] Platform/ARM/Sgi: Add initial support for RD-Daniel Config-XLR platform

["Aditya Angadi" <aditya.angadi@arm.com>]

Arm's RD-Daniel Config-XLR platform is a quad chip platform with each
chip having four Neoverse cores and 8GB of RAM attached to it. These
chips are coherently connected over CCIX interface. Add initial support
for this platform.
