nl80211: Add support to notify radar event info received from STA
Currently radar detection and corresponding channel switch is handled
at the AP device. STA ignores these detected radar events since the
radar signal can be seen mostly by the AP as well. But in scenarios where
a radar signal is seen only at STA, notifying this event to the AP which
can trigger a channel switch can be useful.
Stations can report such radar events autonomously through Spectrum
management (Measurement Report) action frame to its AP. The userspace on
processing the report can notify the kernel with the use of the added
NL80211_CMD_NOTIFY_RADAR to indicate the detected event and inturn adding
the reported channel to NOL.
