For the NL80211_REGDOM_SET_BY_USER hint from cfg80211, it set the new alpha2 code to ath11k, then ath11k send WMI_SET_INIT_COUNTRY_CMDID to firmware for all chips currently. When test with WCN6855/QCA6390 chips, this WMI CMD leads firmware crash. For AP based chips(ipq8074/qcn9074), WMI_SET_INIT_COUNTRY_CMDID is used to send to firmware, for STATION based chips(WCN6855/QCA6390), 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 QCA6390/WCN6855.
