This patch provides a pinctrl driver based on SCMI pin control protocol.
Currently, only the PINCTRL_CONFIG_SET command is implemented.

I have posted a couple of pinctrl patches to [1] , that should simplify
this pinctrl implementation. The entire series is also available in [2]
, the updated mx95 pinctrl patch on top of it is [3] .
