On some SoCs (hello SM6375) vdds-supply is not wired to any smd-rpm
or rpmh regulator, but instead powered by the VDD_MX/mx.lvl line,
which is voted for in the DSI ctrl node.

I think we should have an explicit `if compatible then required:
vdds-supply' clause. WDYT?

Well, the driver will still probe and function without it,
so I'm not sure if it's strictly required..
