dt-bindings: msm/dp: List supplies in the bindings
We're supposed to list the supplies in the dt bindings but there are none in the DP controller bindings. Looking at the Linux driver and existing device trees, we can see that two supplies are expected: - vdda-0p9-supply - vdda-1p2-supply Let's list them both in the bindings. Note that the datasheet for sc7280 doesn't describe these supplies very verbosely. For the 0p9 supply, for instance, it says "Power for eDP 0.9 V circuits". This this is obvious from the property name, we don't bother cluttering the bindings with a description.
