MdePkg: Update EFI_RESOURCE_ATTRIBUTE_READ_ONLY_PROTECTABLE to 0x00080000
MdePkg: Update EFI_RESOURCE_ATTRIBUTE_READ_ONLY_PROTECTABLE to 0x00080000

Previous PI spec (< PI1.4a) has EFI_RESOURCE_ATTRIBUTE_PERSISTENT and
EFI_RESOURCE_ATTRIBUTE_READ_ONLY_PROTECTABLE with same value 0x00800000.

To resolve the conflict, PI1.4a updated
EFI_RESOURCE_ATTRIBUTE_READ_ONLY_PROTECTABLE to 0x00080000, this patch
is to follow PI1.4a spec to update the code.
