The CS5530 at least shouldn't care what order changes are done. I don't
think the SC1200 does either but I don't have the docs to hand.
For libata we went the post_set_mode way and then junked it. Instead
there is a ->set_mode method which defaults to the usual order and
actions. IT821x and similar override it to do very little, post_set_mode
people call the default method and then do their stuff, and some of the
crazier cases do stuff both before and after the default.
Much more flexible and it can do anything unlike flags for the cases you
have.
