ar8216: add ARL table flushing per port

Browse Source 
Adds functions for flushing ARL table entries per port.

Successfully tested on AR8327. Implementation for AR8216/AR8236/AR8316
is based on the AR8236 datasheet and assumes that the three chips
share a common ATU register layout.
Compile-tested only for AR8216/AR8236/AR8316.
