[PATCH 1/1] pinctrl: Add OF dependency for PINCTRL_GENERIC_MUX

[Frank Li]

Add an explicit OF dependency for PINCTRL_GENERIC_MUX to ensure the
generic mux support is only enabled when device tree is available.

Also fix the stub implementation of pinctrl_generic_to_map() by correcting
its last argument to match the non-stub prototype.

when rebase since it is located another fixes tree.

Having been baited into sending a fix for the incorrect signature cos
the commit message here suggested that this was a dependency fix for
just the driver, I think this should be split into two patches,
especially since the commits fixed by each hunk here are different.

Additionally, looks like you're also missing fixes tags.

Cheers,
Conor.
