mb/google/brya/var/xol: Enable FSP UPD LpDdrDqDqsReTraining
Set LpDdrDqDqsReTraining to 1 for xol. Value 0 will cause black screen
issue.
Reference: https://review.coreboot.org/c/coreboot/+/79527
> FSP default value for LpDdrDqDqsReTraining is 1. For boards
> that didn't set LpDdrDqDqsReTraining to any value, 0 was being
> assigned and it caused black screen issue.
BUG=b:332980211
BRANCH=brya
TEST=Built and verified there is no black screen issue during power
on/off test for over 100 cycles.
