Mediatek MT6392 Regulator

Required properties:
- compatible: "mediatek,mt6392-regulator"
- mt6392regulator: List of regulators provided by this controller. It is named
  according to its regulator type, buck_<name> and ldo_<name>.
  The definition for each of these nodes is defined using the standard binding
  for regulators at Documentation/devicetree/bindings/regulator/regulator.txt.

The valid names for regulators are::
BUCK:
  buck_vproc, buck_vsys, buck_vcore
LDO:
  ldo_vxo22, ldo_vaud22, ldo_vcama, ldo_vaud28, ldo_vadc18, ldo_vcn35,
  ldo_vio28. ldo_vusb, ldo_vmc, ldo_vmch, ldo_vemc3v3, ldo_vgp1, ldo_vgp2,
  ldo_vcn18, ldo_vcamaf, ldo_vm, ldo_vio18, ldo_vcamd, ldo_vcamio, ldo_vm25,
  ldo_vefuse

		compatible = "mediatek,mt6392", "mediatek,mt6323";
		mediatek,system-power-controller;
