wifi: cfg80211: add support to handle incumbent signal detected event from mac80211/driver
When any incumbent signal is detected by an AP/mesh interface operating
in 6 GHz band, FCC mandates the AP/mesh to vacate the channels affected
by it [1].
Add a new API cfg80211_incumbent_signal_notify() that can be used
by mac80211 or drivers to notify the higher layers about the signal
interference event with the interference bitmap in which each bit
denotes the affected 20 MHz in the operating channel.
Add support for the new nl80211 event and nl80211 attribute as well to
notify userspace on the details about the interference event. Userspace is
expected to process it and take further action - vacate the channel, or
reduce the bandwidth.
