[PATCH v2 1/2] dt-bindings: regulator: rpi-panel-v2: Add required vcc-supply property

[Shashank Maurya]

Add a vcc-supply property to the Raspberry Pi 7" touchscreen panel V2
regulator binding and mark it as required. The panel controller MCU
needs an external power rail to be supplied before any I2C communication
can take place.
