By default, mdiobus_alloc() sets the PHY's to polling mode, but a
pointer size memcpy means that couple IRQs (depending
on 32-bit or 64-bit kernels) end up being overwritten with
a value of 0. This means that PHY_POLL is disabled and results
in unpredictable behavior depending on the PHYs location on the mdio
bus. Remove that memcpy and the now unused phy_irq member to force
SMSC911x PHY's into polling mode 100% of the time.
