[PATCH V4 1/7] dt-bindings: pinctrl: extend the pinmux property to support integers array

[Dong Aisheng <aisheng.dong@xxxxxxx>]

Some platforms may need more than one integer to represent a complete
pinmux binding, so let's extend the pinmux property to allow to accept
integer array instead of only a single integer.
