Vagiz Trakhanov 771be480a6 nb/sandybridge: Add a kconfig option to ignore XMP max DIMMs
XMP profiles can have a restriction on max supported DIMMs per channel,
but many configurations work with more DIMMs.

This is relevant on mainboards with 2 DIMM slots per channel (usually 4
in total). Populating both slots with DIMMs that support XMP profiles only
with 1 DIMM per channel turns off said XMP profiles.

TEST=On a system with two DIMM slots per channel populate both slots on
one channel and ensure that DIMMs run with XMP profiles enabled.
