Vlv2TbltDevicePkg/PlatformInitPei: Workaround unaligned SMRAM size

Browse Source 
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
