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 Glymur CRD board to UART console with rootfs on nvme storage.
DISPCC enabled as module, used for display.

Is TCSRCC also required for serial?

Not required for serial, will update to m in next rev

Missing spaces before ,
