Testing it, that patch definitely cuts down on recompiles after

     touch include/linux/pinctrl/devinfo.h

a lot.

It still ends up rebuilding a fair amount of odd drivers, but now the
files it rebuilds at least make _some_ sense.

It used to really rebuild just about everything (because pretty much
everything includes <linux/device.h>). Now it rebuilds various snd/soc
files,gpio stuff and mmc/mfc stuff.

I'm sure it could be improved upon still, but I think this is already
a fairly noticeable improvement.

One odd header include down. Ten million to go.
