Add base support for cameras for mt8365 platforms. This requires nodes
for the sensor interface, camsv, and CSI receivers.

Names must be generic. This is mipi-csi-phy@xyz or csi-phy@xyz as it looks
like it's not the entire CSI interface but just its PHY. Am I wrong?

Same for this one.

...so the secondary CSIPHY only supports DPHY, while the first one supports either
C or D?

...and then, it's confusing, one CSI has got one PHY cell, one has got two?

Empty ports, why?
