5f8e077c0a ath9k: simplify regulatory code
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.

4febf7b8f4 ath9k: remove ath9k_hw_chan2wmode()
The only left users are for timing for ACK timeout, slotime and
CTS timeout. We currently use an array CLOCK_RATE to keep
these values per mode and since as only will use A and G
we can depend on the band to get the appropriate values.

We note that we should be using a different clock rate value
for CCK, we can do this in separate patch, currently this is
being disregarded and should only affect when we want to
change the default ACK/CTS timeout or slot time and stuck
with using using 802.11b.

ANI we re-enable the MIB interrupt. Since ANI works

advantage of this and also report a non-static noise
