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 help and ok miod@ from NetBSD
