[PATCH v6 7/8] dt-bindings: pinctrl: mediatek,mt6779-pinctrl: Document MT6735 pin controller

[Yassine Oudjana]

From: Yassine Oudjana <y.oudjana at protonmail.com>

Add bindings for the pin controllers found on MediaTek MT6735 and
MT6735M SoCs. The pin controllers on those SoCs are generally
identical, with the only difference being the lack of MSDC2 pins
(198-203) on MT6735M.
