Subject: [PATCH v3 02/12] regulator: dt-bindings: mt6358: Convert to DT schema
Convert this from the old style text based binding to the new DT schema
style. This will make adding the MT6366 portion easier.
The examples have been trimmed down considerably, and the remaining
entries now match what is seen in actual device trees, minus some
properties that aren't covered by the bindings yet, or don't make
sense on their own.
The original submitter seems to have left MediaTek, so instead the
submitter and maintainer for the MT6366 binding is listed.

Changes since v2:
- Added missing end-of-string match to regulator names
- regulator-coupled-* properties in example dropped
- #include and regulator-allowed-modes moved to new patch

-MediaTek MT6358 Regulator
-
-All voltage regulators provided by the MT6358 PMIC are described as the
-subnodes of the MT6358 regulators 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_vdram1, buck_vcore, buck_vpa, buck_vproc11, buck_vproc12, buck_vgpu,
- buck_vs2, buck_vmodem, buck_vs1
-LDO:
- ldo_vdram2, ldo_vsim1, ldo_vibr, ldo_vrf12, ldo_vio18, ldo_vusb, ldo_vcamio,
- ldo_vcamd, ldo_vcn18, ldo_vfe28, ldo_vsram_proc11, ldo_vcn28, ldo_vsram_others,
- ldo_vsram_gpu, ldo_vxo22, ldo_vefuse, ldo_vaux18, ldo_vmch, ldo_vbif28,
- ldo_vsram_proc12, ldo_vcama1, ldo_vemc, ldo_vio28, ldo_va12, ldo_vrf18,
