Sudhakar Rajashekhara 5a4b131508 davinci: Add EMAC support for da850/omap-l138 
Ethernet Media Access Controller (EMAC) on da850/omap-l138
supports 10/100 Mbps operation. It also supports Media
Independent Interface (MII) and Reduced Media Independent
Interface (RMII) to physical layer (PHY).

Phy which supports MII is present on the DA850/OMAP-L138
base board and Phy supporting RMII is present on the
UI card. This patch adds support only for the MII Phy.
Support for RMII Phy will be added later.
