[U-Boot] [U-boot] [Patch v2 4/5] net: keystone_net: increase MDIO clock frequency

[Ivan Khoronzhuk]

From: Vitaly Andrianov <vitalya at ti.com>

With MAC_PHY sgmii configuration, u-boot checks PHY link status before
sending each packet. Increasing MDIO frequency increases overall tftp
speed. We set it to maximum 2.5MHz.
