The port@0 is a mandatory port, add or move the declaration to the CSI-2
nodes top declared in dtsi files instead of depending on dts files
adding them when describing the external connection.

This fixes validation warnings for DTB outputs that does not connect all
CSI-2 receivers to transmitters and thus declaring all port@0 nodes in
dts files.

I wonder if we should also add #address-cells and #size-cells. That
could simplify the board DT files, but on the other hand, as this is a
CSI-2 input, having multiple endpoints would probably be very rare. It's
probably good enough to leave it as-is.

Trusting that you've addressed all occurrences,
