The Qualcomm SA8775p MDSS display block comes with eDP phy, already used
in DTS and already documented in phy/qcom,edp-phy.yaml binding. Add the
missing device node in the binding and extend example to silence
dtbs_check warnings like:
sa8775p-ride.dtb: display-subsystem@ae00000: Unevaluated properties are not allowed ('phy@aec2a00', 'phy@aec5a00' were unexpected)

Changes in v2:
1. Fix reg size (address/size cells =1) in the example (Rob)
