iwlwifi: reorder device setup

It is better to first notify cfg80211 about the hw
rfkill state (so the rfkill device that will be
registered won't have the wrong state while being
registered), and the power/tt variable init can
(and probably should) also be done first.

Also rename iwl_setup_mac to
iwl_mac_setup_register to better describe what it
really does.
