WLAN hardware might support various hardware modes such as DBS (dual band simultaneously), SBS (single band simultaneously) and DBS_OR_SBS etc, see enum wmi_host_hw_mode_config_type. Firmware advertises actual supported modes in WMI_SERVICE_READY_EXT_EVENTID event. For each mode, firmware advertises frequency range each hardware MAC can operate on. In MLO case such information is necessary during vdev activation and link selection (which is done in following patches), so add a new structure ath12k_svc_ext_info to ath12k_wmi_base, then parse and save those information to it for later use.
