gxfb: stop sharing code with gx1fb
We want to stop sharing stuff with gx1fb; it makes little sense. There were
fields in geodefb_par that weren't being used, there was little point to the
DC/VP ops callbacks, etc. This implements the following:
- Create gxfb_par (based on geodefb_par), place it in gxfb.h
- Drop display_gx.h and video_gx.h. The last few patches moved most
stuff into gxfb.h anyways, so there was very little left.
- Drop the geode_{dc,vid}_ops stuff. Un-static functions, add
declarations to gxfb.h.
