qcacmn: Refine DFS object allocation for MCL

Currently DFS object can only be allocated if radio supports 5G.

Rome supports 5G and saves its wireless_mode in hal_reg_cap of
psoc->service_param because Rome FW does not support wmi event
wmi_service_ready_ext_event_id.

Check wireless_modes based on different DFS_SUPPORT.
