Vlv2TbltDevicePkg/PlatformInitPei: Workaround unaligned SMRAM size
https://bugzilla.tianocore.org/show_bug.cgi?id=260
The PiSmmCPuDxeSmm module requires the SMRR base address and length
to be aligned. The memory initialization for Vlv2TbltDevicePkg
produces an SMRAM base address that is on a 16MB boundary and an
SMRAM length of 12MB. The SMRAM length is rounded up to 16MB.
This is a workaround until the binary module that produces the
gEfiSmmPeiSmramMemoryReserveGuid HOB is updated
