wifi: mac80211_hwsim: add incumbent signal interference detection support

Browse source

Add a debugfs 'simulate_incumbent_signal_interference' with custom
file_operations and a .write that accepts "<freq_mhz> <bitmap>". The
handler selects the 6 GHz chanctx whose primary 20 MHz center matches
<freq_mhz> and reports the event via cfg80211_incumbent_signal_notify().
The bitmap marks affected 20 MHz segments within the current chandef
(lowest bit = lowest segment)
