net: dsa: rtl8366rb: Support fast aging 



This implements fast aging per-port using the special "security"
register, which will flush any learned L2 LUT entries on a port.

The vendor API just enabled setting and clearing this bit, so
we set it to age out any entries on the port and then we clear
it again.
