[Jonathan Zhang (Code Review)]

Hello build bot (Jenkins), Marc Jones, Johnny Lin, Angel Pons, Subrata Banik, Patrick Rudolph, Tim Chu,

I'd like you to reexamine a change. Please visit

to look at the new patch set (#4).

vc/intel/FSP2_0/CPX-SP: add FSPM DIMM watermark option

FSPM MemRefreshWatermark option support is present in FB's CPX-SP
FSP binary, but not in Intel's CPX-SP FSP binary.

In CPX-SP soc code, add a Kconfig HAVE_FSPM_DIMM_WATERMARK_OPTION to
indicate whether the FSP binary supports such option.

For DeltaLake mainboard, when such option is set, if corresponding
VPD variable is set, use it to control the behavior.
