soc/intel/adl: Allow mainboard to fill CmdMirror and DqDqsRetraining 

We need to modify update CmdMirror and LpDdrDqDqsRetraining parameters
for ADLRVP board.
Allowing this parameters to be filled by devicetree will allow
flexibility to update values as per board designs.
Note that both UPDs are applicable for both DDR and Lpddr memory types.

BUG=None
BRANCH=None
TEST=Build works and UPD values have been filled correctly
