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. Signed-off-by: Cyril Chemparathy <cyril@ti.com> Acked-by: David S.
