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 Change-Id: I073186674a1a593547d1ee1d15c7cd4fd8ad5bc1 Signed-off-by: T Michael Turney <mturney@codeaurora.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/25208 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Julius Werner <jwerner@chromium.org>
