net: mvmdio: enhance driver to support SMI error/done interrupts
This patch enhances the "mvmdio" to support a SMI error/done interrupt line which can be used along with a wait queue instead of doing busy-waiting on the registers. This is a feature which is available in the mv643xx_eth SMI code and thus reduces again the gap between the two.

The child nodes of the MDIO driver are the individual PHY devices
connected to this MDIO bus. They must have a "reg" property given the
PHY address on the MDIO bus.
