Subject: [RFC v6 net-next 1/9] pinctrl: ocelot: allow pinctrl-ocelot to be loaded as a module

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.

This is fine to merge through the netdev tree, if you prefer I merge patches
1 & 2 to the pinctrl tree just tell me.

I'd thought about splitting these out, but they really don't make much
sense to be anywhere until the MFD is added in. The big one I needed in
pinctrl was the regmap conversions that are in 5.17-rc1, so I'm hopeful
I won't need to bounce back and forth much moving forward.

Thanks for reviewing!
