ath11k: avoid firmware crash when reg set for QCA6390/WCN6855
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.
Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03003-QCAHSPSWPL_V1_V2_SILICONZ_LITE-2
