powerpc/mpc85xx: implement workaround for errata DDR111 and DDR134
Workaround for the following errata: DDR111 - MCKE signal may not function correctly at assertion of HRESET DDR134 - The automatic CAS-to-Preamble feature of the DDR controller can calibrate to incorrect values These two workarounds must be implemented together because they touch common registers.
