add gpio-hog support. GPIO hogging is a mechanism providing automatic GPIO request and configuration as part of the gpio-controller's driver probe function.

I have tested it on zcu102 where I use gpio hogs for gt muxes. gpio hogs are handled and setup only when gpio controller is probed. Do we have a way how to say that controllers with gpio hogs should be probed automatically?
Right now you are calling it in post_probe which make sense but on the other hand if you find gpio hog in bind you should probe the whole driver without asking for request.
