    ath11k: avoid firmware crash when reg set for QCA6390/WCN6855 · 0d6e997b

    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.
