wifi: cfg80211: allow IR in 20 MHz configurations

Browse Source 
Some regulatory bodies doesn't allow IR (initiate radioation) on a
specific subband, but allows it for channels with a bandwidth of 20 MHz.
Add a channel flag that indicates that, and consider it in
cfg80211_reg_check_beaconing.

While on it, fix the kernel doc of enum nl80211_reg_rule_flags and
change it to use BIT().
