        src/sys/arch/sh3/include: cache.h pmap.h
        src/sys/arch/sh3/sh3: cache.c cache_sh4.c pmap.c

Log Message:
Allow shared PV mappings in pmap_enter(9) even on SH4 if VAs of shared pages
have the same virtual cache indexes (i.e. they won't cause virtual cache
aliases). Also prepare PMAP_PREFER(9) for SH4 to avoid some possible virtual
cache aliases.
More stuff should be added in pmap_enter(9), but at least this changes
should fix some existing problems. See discussion on port-sh3 ML for details.

OK'ed by uwe and chs, and closes PR port-sh3/34243.
