intel/skylake: Fix RMT disable of saved training data
The RMT flag that was attempting to disable saved training to
force a full memory train was happening too late. In testing
I was actually hitting a case where FSP was training every time
but it was not because it was properly being told to.
This moves the check of the RMT flag from devicetree to happen
ealier, before it is actually consumed by romstage_common().
BUG=chrome-os-partner:40635
BRANCH=none
TEST=do both power off+on and warm resets to ensure that FSP
is doing a full memory train every time with RMT enabled.
