intel/skylake: Force full memory train if RMT is enabled
RMT is useless if the memory does not do a full training pass, and since FSP does not seem to handle that case itself have coreboot not pass in a valid set of saved training data so FSP will do a full memory train.
BUG=chrome-os-partner:40635 BRANCH=none TEST=build and boot twice on glados with p2 and RMT enabled and see it do a full memory train on each boot.
