net: fs_enet: set back promiscuity mode after restart 

After interface restart (eg: after link disconnection/reconnection), the bridge
function doesn't work anymore. This is due to the promiscuous mode being cleared
by the restart.

The mac-fcc already includes code to set the promiscuous mode back during the restart.
This patch adds the same handling to mac-fec and mac-scc.

Tested with bridge function on MPC885 with FEC.
