[PATCH v5][edk2-platforms 17/17] Platform/ARM/SgiPkg: 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 and are put together
into a multi-chip package. Add initial support for this platform.
