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.
