net: davinci_emac: switch to new mdio
This patch switches the emac implementation over to the newly separated
MDIO driver.
With this, the mdio bus frequency defaults to a safe 2.2MHz. Boards may
optionally specify a bus frequency via platform data.
The phy identification scheme has been modified to use a phy bus id instead
of a mask. This largely serves to eliminate the "phy search" code in emac
init.
