Add handler for WMI_11D_SCAN_START_CMDID, WMI_11D_SCAN_STOP_CMDID. Use WMI_11D_SCAN_START_CMDID to trigger 11d scan then firmware will report 11d scan result by WMI_11D_NEW_COUNTRY_EVENTID. Host will update the new country code back to firmware. The priority of 11d scan is WMI_SCAN_PRIORITY_MEDIUM in firmware, the priority of hw scan is WMI_SCAN_PRIORITY_LOW. Then hw scan will be canceled when 11d scan is running. To avoid this, need to change the priority of first hw scan to WMI_SCAN_PRIORITY_MEDIUM. Add wait_for_completion_timeout() for scan.complete in ath12k_reg_update_chan_list(). Plus another existing wait in ath12k_scan_stop(), there are two places to wait the scan.complete. They run in different threads so it is possible that both of the enter into wait status. Therefore use complete_all() instead of complete() for scan.complete. complete_all() can work well when it is only one thread wait for scan.complete.
