Subject: [PATCH net-next] net: bcmgenet: Remove custom ndo_poll_controller()

The driver gained a .ndo_poll_controller() at a time where the TX
cleaning process was always done from NAPI which makes this unnecessary.
See commit ac3d9dd034e5 ("netpoll: make ndo_poll_controller() optional")
for more background.
