The conversation above concluded that a hwpt should only enforce cache
coherency per device at the stage of its allocation, and it should not
be changed or updated in the attach/replace routines.

Add two patches dropping the enforce_cache_coherency calls from attach
and replce routines respectively, since they were introduced with two
different commits.
