Put this in device.h instead?

I have finally moved the driver core to only accept/need "groups" not a
single "group", so we should only need devm_sysfs_create_groups and
devm_sysfs_remove_groups, right?

And do we need/want the non-devm versions:
	device_create_groups()
	device_remove_groups()
?

And you can probably drop the 'sysfs' from the function name if you
want.
