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.

Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (v6.4/arm64-dt)

These changes has been applied on the intermediate git tree [1].

The v6.4/arm64-dt branch will then be sent via a formal Pull Request to the Linux SoC maintainers
for inclusion in their intermediate git branches in order to be sent to Linus during
the next merge window, or sooner if it's a set of fixes.

In the cases of fixes, those will be merged in the current release candidate
kernel and as soon they appear on the Linux master branch they will be
backported to the previous Stable and Long-Stable kernels [2].

The intermediate git branches are merged daily in the linux-next tree [3],
people are encouraged testing these pre-release kernels and report issues on the
relevant mailing-lists.

If problems are discovered on those changes, please submit a signed-off-by revert
patch followed by a corrective changeset.
