[PATCH 1/3] dt-bindings: drm/bridge: adv7511: Add regulators for ADV7533

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

Add the regulator supply properties needed for ADV7533. The regulator
names are named after the pin names. The exact use of each supply isn't
clear from the data sheets.

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.

There might be a similar set of regulators for ADV7511, but we don't
have the docs at the moment to find out what supplies it needs. The
regulator properties needed by ADV7511 can be updated as we get more
data on it.
