Add support for both the BananaPi BPI-CM4 module and the BananaPi
baseboard which is comnpatible with the RaspberryPi CM4IO baseboard.
The BananaPi BPI-CM4 module follows the CM4 specifications at [1],
but with a single HDMI port and a since DSI output.
The current CM4IO baseboard DT should work fine on the Raspberry CM4
baseboard and other derivatives baseboards, but proper DT should
be written for other baseboards.
The split is done so it's easy to describe a new CM4 baseboard, enabling
only the necessary HW used on the baseboard.
