arm64: dts: qcom: apq8016-sbc-d3-camera: Convert to DT overlay
Follow the example of the recently added apq8016-sbc-usb-host.dtso and
convert apq8016-sbc-d3-camera-mezzanine.dts to a DT overlay that can be
applied on top of the apq8016-sbc.dtb. This makes it more clear that
this is not a special type of DB410c but just an addon board that can
be added on top.
Functionally there should not be any difference since
apq8016-sbc-d3-camera-mezzanine.dtb is still generated as before
(but now by applying the overlay on top of apq8016-sbc.dtb).
Since dtc does not know that there are default #address/size-cells in
msm8916.dtsi, repeat those in the overlay to avoid dtc warnings because
it expects the wrong amount of address/size-cells.
It would be nice to have a generic overlay for the D3 camera mezzanine
(that can be applied to all 96Boards) but that's much more complicated
than providing a board-specific DT overlay as intermediate step.
