Subject: [PATCH v2 1/7] regulator: dt-bindings: mt6323: Convert to DT schema
Convert this from the old style text based binding to the new DT schema
style.
The examples have been trimmed down and move to parent schema
mfd/mediatek,mt6397.yaml.
Add new maintainers and submitter from MediaTek.

Changes for v1 and v2:
- This is the first version of converting mt6323-regulator.
This is because converting mt6323-regulator together
with mfd/mediatek,mt6397.yaml, so we've create a patch set
instead of single patch for each skydives.
- This patch has been made base on linux-next/master git repo.

-Mediatek MT6323 Regulator
-
-All voltage regulators are defined as subnodes of the regulators node. A list
-of regulators provided by this controller are defined as subnodes of the
-PMIC's node. Each regulator 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_vpa
-LDO:
- ldo_vtcxo, ldo_vcn28, ldo_vcn33_bt, ldo_vcn33_wifi, ldo_va, ldo_vcama,
- ldo_vio28, ldo_vusb, ldo_vmc, ldo_vmch, ldo_vemc3v3, ldo_vgp1, ldo_vgp2,
- ldo_vgp3, ldo_vcn18, ldo_vsim1, ldo_vsim2, ldo_vrtc, ldo_vcamaf, ldo_vibr,
