ar8216: add ARL table flushing per port
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. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> SVN-Revision: 46380
