powerpc/mpc8548: Add workaround for erratum NMG_DDR120
Erratum NMG_DDR120 (DDR19 in MPC8548 errata document) applies to some
early version silicons. The default settings of the DDR IO receiver
biasing may not work at cold temperature. When a failure occurs,
a DDR input latches an incorrect value. The workaround will set the
receiver to an acceptable bias point.
