From: Yassine Oudjana <y.oudjana@protonmail.com>
Add bindings for the pin controller found on MediaTek MT6735 and MT6735M SoCs, including describing a method to manually specify a pin and function in the pinmux property making defining bindings for each pin/function combination unnecessary. The pin controllers on those SoCs are generally identical, with the only difference being the lack of MSDC2 pins (198-203) on MT6735M.
