MPC5XXX, Motion-PRO: Fix PHY initialization problem.
After being reset in mpc5xxx_fec_init_phy(), PHY goes into FX mode, in which
networking does not function. This commit switches PHY to TX mode by clearing
the FX_SEL bit of Mode Control Register. It also reverses commit
008861a2f3ef2c062744d733787c7e530a1b8761, i.e., a temporary workaround.
