OvmfPkg: PlatformPei: allow caching in AddReservedMemoryBaseSizeHob()
AddReservedMemoryBaseSizeHob() should be able to set the same resource
attributes for reserved memory as AddMemoryBaseSizeHob() sets for system
memory. Add a new parameter called "Cacheable" to
AddReservedMemoryBaseSizeHob(), and set it to FALSE in the only caller we
have at the moment.
