85xx: Add CPU 2 errata workaround to all 8548 boards
All mpc8548-based boards should implement the suggested workaround to CPU 2 errata. Without the workaround, its possible for the 8548's core to hang while executing a msync or mbar 0 instruction and a snoopable transaction from an I/O master tagged to make quick forward progress is present.
