[PATCH 2/2] ARM: meson: Add initial support for BPI-CM4 module with BPI-CM4IO baseboard

[Neil Armstrong]

Add support for both the BananaPi BPI-CM4 module and the BananaPi
baseboard which is compatible with the RaspberryPi CM4IO baseboard.

The BananaPi BPI-CM4 module follows the CM4 specifications at [1],
but with a single HDMI port and a single 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.
