Restructure the ath11k_mac_setup_iface_combinations function to support DBS and DFS compatibility. About 'support_dual_station' feature can refer: https://msgid.link/20230714023801.2621802-2-quic_cjhuang@quicinc.com Add a ieee80211_iface_combination to support DBS and DFS compatibility, one combination can support DFS(same with non dual sta), another combination can support DBS. When running different scenarios that will use different ieee80211_iface_combination due to mac80211 will go through all of possible interface combinations. In addition, maximum number of interfaces of these types should be total allowed in this group. The chips affected are: QCA6390 hw2.0 WCN6855 hw2.0 WCN6855 hw2.1 Other chips are not affected.
