soc/qualcomm/sc7280: DDR One-Time-Training Support
Introduce DDR One-Time-Training Support
Device reboots without training from second iteration
and also DDR training data is 32kb size, hence update
required in memlayout and to sync with upstream changes
the Fmap size even got bumped up.
BUG=b:182963902
TEST=Validated on qualcomm sc7280 development board
