disabled with memory region attributes instead of by the global
variable "remotecache". Add comment describing the interaction
between dcache and memory region attributes.
(dcache_xfer_memory): Add comment describing benefits of moving
cache writeback to a higher level.
(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. However, this is not needed because the
cache is write through and the code that enables, disables, and
deletes memory regions invalidate the cache. Add comment which
suggests that we could be more selective and only invalidate those
cache lines containing data from those memory regions.

perform a uncached transfer if dcache_enabled_p was clear. This
function is now only called if caching is enabled for the memory
region.
