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.
