dt-bindings: msm/dp: handle DP vs eDP difference
The #sound-dai-cells property should be used only for DP controllers. It
doesn't make sense for eDP, there is no support for audio output. The
aux-bus should not be used for DP controllers. Also p1 MMIO region
should be used only for DP controllers.
Take care of these differences.
