drivers: pinctrl: add pinctrl support

Add support for pinctrl support using device-tree. The device-tree
"pinctrl-<x>" and "pinctrl-names" properties are supported and
allows to apply a pinctrl configuration based on this. This support
also includes a way to register pin muxing controllers that can apply
these states.
A few properties of the pinctrl nodes are supported such as
"bias-disable", "bias-pull-up" and "bias-pull-down".
