[PATCH v4 1/6] mfd: dt-bindings: mt6397: Add regulator supplies

[Chen-Yu Tsai <wenst@chromium.org>]

On the MT6397 family each buck regulator has a separate supply. LDOs are
split into various groups with independent supplies. There is also a
supply for the regulator control logic.

Add descriptions for all of the supplies for the MT6359.

Lee, request from Mark:

Lee, this seems like mostly a regulator series - OK for me to apply this
patch and send you a tag for it?

Changes since v3:
- Dropped duplicate 'va09' from 'vsys-ldo2-supply' (Sashiko)

Changes since v2:
- Fix vsys-vsmps-supply property name

Changes since v1:
- Use regular expression to describe vcn33_* names
- Moved regulator supplies to top level PMIC node
- Moved changes to mfd binding
