kernel: ar8327/ar8337: disable ARL access code to avoid lockups (FS#384)
Running ar8327_get_arl_entry() early after boot leads to MDIO related system lockups on several devices using this driver. Since dumping the ARL table contens is an optional, uncritical feature, simply disable the code for now. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
