ARM: dts: import initial DT for BPI-CM4 module with BPI-CM4IO baseboard
Import initial support for BPI-CM4 module with BPI-CM4IO baseboard
from the Linux submission applied at [1].
The BananaPi BPI-CM4 module follows the CM4 specifications at [2],
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.
