I'd prefer to have three patches here:
- One that add the controllers
- One that add the pin muxing options
- One that enable the controllers on the various boards.

This can be made a single pinctrl group, you don't need the pinctrl-1
stuff, it only complicates the node.

This belongs to the board, the controller itself is able to handle
several bus width.
