mac80211: make software rate control optional
Some devices implement the entire rate control in firmware in some way, like wl1271 or like iwlwifi which does some things in software but not a lot. Therefore generic software rate control is rather useless for them and just adds avoidable overhead to the transmit path. It's fairly simple to let drivers indicate that they do not need rate control, but they need to fulfil a number of conditions that we encode in WARN_ONs.
