wifi: rtw89: improve scan time on 6 GHz band

Browse source

Reduce scan time for all supported channels from 4.4s to 3.5s.

If NL80211_SCAN_FLAG_COLOCATED_6GHZ is set in scan request, only scan PSC
channels and the channels from the RNR element found on the 2.4/5 GHz
channels. When firmware support parsing RNR element from received beacon
or probe response, offload the decision about non-PSC channels to firmware.
Driver do not need to fill non-PSC channels to scan list. If
NL80211_SCAN_FLAG_COLOCATED_6GHZ is not set, scan all supported channels.
