Subject: overhaul the grf driver:

- Simplify grfmv_phys() to work like grfiv_phys(), and eliminate the
  second argument to both, as we don't use it anyway.
- Handle fbbase and fboff consistently throughout.
- Eliminate grfaddr() by pulling it into grfmmap(), which is the
  only place it was used, previously.
- grfmap() now gets the physical address of the framebuffer from
  the appropriate driver, rather than try to compute it by itself.
  Be careful with aligning the base to a page address and increase
  the length of the mapped region appropriately.
- Store the PA of the framebuffer in the softc.  This eliminates the need
  for the sc_phys callback; we can just store the PA in the grfbus attach
  args, rather than a function pointer, which simplifies the code nicely.
- Disable Valkyrie interrupts on the Quadra 630
- New and improved console framebuffer initialization and autoconfig.  This
  resolves a great many issues, including Performa 58x interrupt handling
  and offset displays on some models.
- Remove unused grf ioctls
- Some KNF and other minor things
