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]+'
