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 require boards that used on GT5663 can enable it via device tree.

I think we normally use lower case in DT bindings and rarely encode voltage in the supply name unless we are dealing with several supplies of the same kind, but I'll let Ron comment on this. Thanks. -- Dmitry
