For the NL80211_REGDOM_SET_BY_USER hint from cfg80211, it set the new alpha2 code to ath12k, then ath12k send WMI_SET_INIT_COUNTRY_CMDID to firmware for all chips currently. When test with WCN7850 chips, this WMI CMD leads firmware crash. For AP based chips(QCN92xx), WMI_SET_INIT_COUNTRY_CMDID is the correct command use. However, for STATION based chips(WCN7850), it need to use another WMI CMD, WMI_SET_CURRENT_COUNTRY_CMDID. Add flag current_cc_support in hardware parameters. It is used to distinguish AP/STA platform. After that, the firmware will work normal and the regulatory feature works well for WCN7850.
