ath9k: add spectral scan feature

Adds the spectral scan feature for ath9k. AR92xx and AR93xx chips
are supported for now. The spectral scan is triggered by configuring
a mode through a debugfs control file. Samples can be gathered via
another relay debugfs file.

Essentially, to try it out:

echo chanscan > /sys/kernel/debug/ieee80211/phy0/ath9k/spectral_scan_ctl
iw dev wlan0 scan
cat /sys/kernel/debug/ieee80211/phy0/ath9k/spectral_scan0 > samples
echo disable > /sys/kernel/debug/ieee80211/phy0/ath9k/spectral_scan_ctl

This feature is still experimental.

The special "chanscan" mode is used to perform spectral scan while
mac80211 is scanning for channels. To allow this,
sw_scan_start/complete() ops have been added.

- reset_regdomains(true);
- cfg80211_regdomain = cfg80211_world_regdom;
+ reset_regdomains(true, cfg80211_world_regdom);

This looks innocent enough, until you realise that the
called function (reset_regdomains) also resets the
cfg80211_world_regdom pointer, so that the old version
of the code would use the new object it pointed to and
the new version of the code uses the old object. This
lead to a double-free of this object.

Since reset_regdomains() sets it to &world_regdom, use
that directly.
