davinci: add mdio platform devices
This patch adds mdio platform devices on SoCs that have the necessary hardware. Clock lookup entries (aliases) have also been added, so that the MDIO and EMAC drivers can independently enable/disable a shared underlying clock. Further, the EMAC MMR region has been split down into separate MDIO and EMAC regions. Signed-off-by: Cyril Chemparathy <cyril@ti.com> Acked-by: David S.
