Changeset 68 for trunk/modules/vci_cc_vcache_wrapper2_v1/caba/source/include/vci_cc_vcache_wrapper2_v1.h

Message:

A SC cause the dcache entry to be updated by the memcache, and the
tlb entry to be invalidated. So just go back to DCACHE_IDLE to redo a lookup.
Assert that the data is not in dcache in CC_CHECK when we're not going
to update/invalidate the cache or tlb.
Drop DCACHE_WRITE_DIRTY state, it's not used any more.
