sfc: do not try to call tc functions when CONFIG_SFC_SRIOV=n

Browse source 
Functions efx_tc_netdev_event and efx_tc_netevent_event do not exist
 in that case as object files tc_bindings.o and tc_encap_actions.o
 are not built, so the calls to them from ef100_netdev_event and
 ef100_netevent_event cause link errors.
Wrap the corresponding header files (tc_bindings.h, tc_encap_actions.h)
 with #if IS_ENABLED(CONFIG_SFC_SRIOV), and add an #else with static
 inline stubs for these two functions.
