s-paulraj@ti.com 7835f4b949 DaVinci Network Driver Updates 
Different flavours of DaVinci SOC's have differences in their EMAC IP
This patch does the following
1) Updates base addresses for DM365
2) Updates MDIO frequencies for DM365 and DM646x
3) Update EMAC wrapper registers for DM365 and DM646x

Patch applies to u-boot-net git. the EMAC driver itself
will be updated shortly to add support for DM365 and DM646x
