[PATCH v2 03/18] dt-bindings: msm: dsi-controller-main: Add vdd* descriptions back in

[Bryan O'Donoghue]

When converting from .txt to .yaml we didn't include descriptions for the
existing regulator supplies.

- vdd
- vdda
- vddio

Add those descriptions into the yaml now as they were prior to the
conversion. Mark the supplies as required as was previously the case in the
.txt implementation.

Warnings about missing regulators can be resolved by updating the relevant
dtsi files to point to fixed always-on regulators where appropriate.
