The serial engine must be properly setup before kernel reaches
"init", so UART driver and its dependencies needs to be built in.
Enable its dependency clocks,interconnect and pinctrl as built-in
to boot Qualcomm's dev platform - Glymur CRD board to UART console with
rootfs on nvme storage.
DISPCC enabled as module, used for display.
