Ard Biesheuvel ef120b7d63 ArmPlatformPkg: remove ArmPlatformInitializeSystemMemory
The function ArmPlatformInitializeSystemMemory() is defined by
ArmPlatformLib, but is only ever called when using the PrePeiCore
flavor of the startup code. Also, none of the remaining upstream
platforms actually implement anything in that function in the first
place. So let's just remove it altogether.
