[PATCH 3/4] net/fec: set phy_speed to the optimal frequency 2.5 MHz

[Shawn Guo]

With the unnecessary 1 bit left-shift on fep->phy_speed during the
calculation, the phy_speed always runs at the half frequency of the
optimal one 2.5 MHz.

The patch removes that 1 bit left-shift to get the optimal phy_speed.
