fec: use interrupt for MDIO completion indication With the move to phylib (commit e6b043d) I was seeing sporadic "MDIO write timeout" messages. Measure of the actual time spent showed latency times of more than 1600us. This patch uses the MII event indication of the FEC hardware to detect completion of MDIO transactions.
