Now that cfg80211 has its own regulatory infrastructure we can
condense ath9k's regulatory code considerably. We only keep data
we need to provide our own regulatory_hint(), reg_notifier() and
information necessary for calibration.
Atheros hardware supports 12 world regulatory domains, since these
are custom we apply them through the the new wiphy_apply_custom_regulatory().
Although we have 12 we can consolidate these into 5 structures based on
frequency and apply a different set of flags that differentiate them on
a case by case basis through the reg_notifier().
If CRDA is not found our own custom world regulatory domain is applied,
this is identical to cfg80211's except we enable passive scan on most
frequencies.

When we try to change the channel in ath9k its because
either the configuration indicates we *have* changed
channels or HT configuration has changed. In both cases
we want to do a reset. Either way mac80211 will inform us
when we want to actually change the channel so trust those
calls.
Although in the patch it may seem as I am doing more code
changes I am not, all I am doing is removing the initial
branch conditional and shifting the code to the left.
