Probably, as well as all the other SoC specific drivers. But I think
this should be a separate patch, its independent from this addition.

But given the remove-panic problems I mentioned earlier this whole
pinctrl-as-module topic needs some attention from more experienced devs
I guess, this is beyond my current kernel knowledge.
