net: uec_phy: handle 88e1111 rev.B2 erratum 5.6
erratum 5.6 states the autoneg completion bit is functional only if the autoneg bit is asserted. This fixes any secondarily-issued networking commands on non-gigabit links on the mpc8360 mds board. Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
