clean up some other stuff along the way, including:
- use m68k/cacheops.*, remove duplicates from cpu.h.
- centralize a few declarations in (all the copies of) cpu.h.
- define M68K_VAC on platforms which have a VAC.
- switch the sun platforms to the (now common) proc_trampoline().
- do the phys_map thang on the sun platforms too, no reason not to.
in new hp300spu.h file. This includes the code that associates
model number with cpu/mmu/cache combinations.
- Define "mmuid" constants for several models, derived from code
provided by Mike Smith.
