Rearange struct mach64screen to be derived from struct rasops_info, 

move a few bits around and make adding screens after attach time
actually work.

When not booting as console, try to properly set up the hardware to
get a display nevertheless (XXX - does not yet work on my U5).

#if 0 some unused functions planned for future extensions (to make clear
they are unused now)
