sdm845: Add QCLib to RomStage to perform IP init

CB acts as I/O handler for QCLib (e.g. DDR training data)
This interface allows bi-directional data flow between
CB and QCLib
Tested and working interfaces:
 DDR Training data
 QCLib serial console output
 DDR Information (base & size)
 limits cfg data
TEST=build & run
