[PATCH v3 1/2] dt-bindings: drm/bridge: adv7511: Add regulator bindings

[Archit Taneja <architt-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>]

Add the regulator supply properties needed by ADV7511 and ADV7533.

The regulators are specified as optional properties since there can
be boards which have a fixed supply directly routed to the pins, and
these may not be modelled as regulator supplies.
