ppc-sam440: Use Write-Through caching for main memory.
Although this will slow down the system, it also means that
AmigaOS drivers/programs do *not* need to special case usage of
CacheClearE() for AROS Sam4xx PowerPC systems.
With WriteThrough enabled for main memory, all CACF_InvalidateD
are safe, since any 'surrounding' data will have already been
written to main memory.
