Work is being done to allow external control of Ocelot chips. When pinctrl
drivers are used internally, it wouldn't make much sense to allow them to
be loaded as modules. In the case where the Ocelot chip is controlled
externally, this scenario becomes practical.

I would have to think hard to remember a single review comment from Andy
where I didn't think "ah, yeah he's right", so definately keep mine.
