Intel CPX-SP FSP ww45 release annotates default values for FSP-M UPD
variables.
FSPM MemRefreshWatermark option support is present in FB's CPX-SP
FSP binary, but not in Intel's CPX-SP FSP binary. In FB's CPX-SP
FSP binary, this option takes the space of UnusedUpdSpace0[0].
For DeltaLake mainboard, if corresponding VPD variable is set, use it
to control the behavior. Such control is effective when FB's CPX-SP
FSP binary is used.

Provide necessary romstage hooks to allow unblocking the memory with
SCLEAN. Note that this is slow, and took four minutes with 4 GiB of RAM.
Tested on Asrock B85M Pro4 with tboot. When Linux has tboot support
compiled in, booting as well as S3 suspend and resume are functional.
However, SINIT will TXT reset when the iGPU is enabled, and using a dGPU
will result in DMAR-related problems as soon as the IOMMU is enabled.
However, SCLEAN seems to hang sometimes. This may be because the AP
initialization that reference code does before SCLEAN is missing, but
the ACM is still able to unblock the memory. Considering that SCLEAN is
critical to recover an otherwise-bricked platform but is hardly ever
necessary, prefer having a partially-working solution over none at all.
