Subject: [PATCH] net/phy: micrel: configure intterupts after autoneg workaround

The commit ("net/phy: micrel: Add workaround for bad autoneg") fixes
an autoneg failure case by resetting the hardware. This turns off
intterupts. Things will work themselves out if the phy
polls, as it will figure out it's state during a poll. However if the
phy uses only intterupts, the phy will stall, since interrupts
are off.

This patch fixes the issue by calling config_intr after resetting the
phy.
