[PATCH v2 1/4] dt-bindings: input: touchscreen: goodix: Document AVDD28-supply property

[Jagan Teki]

Most of the Goodix CTP controllers are supply with AVDD28 pin.
which need to supply for controllers like GT5663 on some boards
to trigger the power.

So, document the supply property so-that the required board
that used on GT5663 can enable it via device tree.
