ArmVirtPkg/ArmVirtQemu: Disable PcdPrePiProduceMemoryTypeInformationHob for ARM

Browse Source 
The PcdPrePiProduceMemoryTypeInformationHob on ARM breaks Linux efistub
boot. The efistub for arm32 uncompresses Linux kernel into memory ranges
which occupied by DXE-phase drivers which leads to
'permission denied'-error during page write. So as a temporary solution
we use PcdPrePiProduceMemoryTypeInformationHob only for AARCH64
