Instead of looking at the PCD gArmTokenSpaceGuid.PcdSystemMemoryBase to decide which DT node covers the memory we are already using, query the GCD memory space map, which is the authoritative source for this kind of information This fixes a problem observed by Michael on platforms where this PCD is of the 'Patchable' type, which means updates to its value do not propagate to other modules.
