Subject: dt-bindings: arm: amlogic: Document the boards with the BPI-CM4
 connected

The BPI-CM4 module with an Amlogic A311D SoC is a module compatible
with the Raspberry Pi CM4 specifications.

Document the boards using this module, by specifying the BananaPi CM4
compatible in addition to the baseboard compatible.

Subject: arm64: dts: amlogic: Add initial support for BPI-CM4 module with
 BPI-CM4IO baseboard

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.
