This patch converts the Marvell MV643XX ethernet driver to use the
Marvell Orion MDIO driver. As a result, PowerPC and ARM platforms
registering the Marvell MV643XX ethernet driver are also updated to
register a Marvell Orion MDIO driver. This driver voluntarily overlaps
with the Marvell Ethernet shared registers because it will use a subset
of this shared register (shared_base + 0x4 - shared_base + 0x84). The
Ethernet driver is also updated to look up for a PHY device using the
Orion MDIO bus driver.

Thanks to the help of Andrew Lunn, there is at least two known issues with this patch version:

- we need to move up the mvmdio line in drivers/net/ethernet/marvell/Makefile to make sure that configs having both mvmdio and mv643xx_eth built-in get the probing order right
- the bus name used by mv643xx_eth is not the right now (orion-mdio.0 vs expected orion-mdio) so the PHY device will not be found during phy_connect()

I will fix these two issues in the next version of the patchset.
