(dcache_struct): Removed cache_has_stuff field. This was used to record whether the cache had been accessed in order to invalidate it when it was disabled.

This function is now only called if caching is enabled for the memory region. (dcache_info): Always print cache info. * target.c (do_xfer_memory): Add attrib argument.
