[PATCH 1/3] dt-bindings: mfd: Add bindings for the MediaTek MT6351 PMIC

[Mars Cheng <mars.cheng-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>]

From: "Jimmy-YJ.Huang" <jimmy-yj.huang-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>

This adds dt-binding documentation for Mediatek MT6351.
Only include mfd and regulator bindings.
