Subject: [PATCH v3 10/22] wifi: nxpwifi: implement cfg80211 ops
Implement needed functions of struct cfg80211_ops to support client
and AP mode on top of NXP FW. Nxpwifi hooks separate auth and assoc
in order to use SAE of wpa_supplicant and hostapd.
Because NXP FW still involves in association process (driver should
use association command to communicate with FW to do association
process), so it is impossible for nxpwifi to leverage mac80211.
