arm64: dts: rockchip: correct panel supplies on Odroid Go Super

The Anbernic and Odroid Go have different panels and take differently
named supplies, so move all the supplies to DTS defining actual panel to
fix warnings like:

  rk3326-odroid-go3.dtb: panel@0: 'IOVCC-supply' is a required property
  rk3326-odroid-go3.dtb: panel@0: 'iovcc-supply', 'vdd-supply' do not match any of the regexes: 'pinctrl-[0-9]+'
