This 32k section of RAM will be declared to the PEI Core on
S3 resume to allow memory allocations during S3 resume PEI.
If the boot mode is BOOT_ON_S3_RESUME, then we publish
the pre-reserved PcdS3AcpiReservedMemory range to PEI.
If the boot mode is not BOOT_ON_S3_RESUME, then we reserve
this range as ACPI NVS so the OS will not use it.
