To: johannes; +Cc: linux-wireless, ath11k
New nl80211 ext_feature and scan_flag added to support wide band scan which
allows driver to scan on requested channel with corresponding
phy mode/bandwidth (40Mhz, 80Mhz).
To handle center frequency of 80Mhz channel, struct cfg80211_chan_def is
included in cfg80211_scan_request.

To: johannes; +Cc: linux-wireless, ath11k
Doing wide band scan instead of normal 20Mhz scan before spectral dump,
allows to fetch FFT reports for the complete requested bandwidth
(40Mhz, 80Mhz).
Below are the FW expectations and configs from host to request
Wide Band Scan,
1. SCAN_PHYMODE_SUPPORT WMI service bit advertised from FW.
2. SCAN_CHAN_LIST_CMD updated with the phymode and other channel params
of the requested channel to do wide band scan.
3. START_SCAN_CMD updated with all the seven supported TLVs and PHYMODE TLV
being the last. PHYMODE TLV holds the (wmi_phy_mode + 1) value
corresponding to wide band scan channel. Scan flags scan_f_wide_band and
scan_f_passive need to be set for wide band scan request from host.
In case of supporting NL80211_EXT_FEATURE_WIDE_BAND_SCAN,
cfg80211_scan_request holds the cfg80211_chan_def of the requested channel
from which we update the center frequencies and phymode params needed for
SCAN_CHAN_LIST_CMD and START_SCAN_CMD to FW.
