Based on Kumar's new compatible types patch, add P2020 into MPC85xx EDAC

compatible lists so that EDAC can recognize P2020 meomry controller and L2
cache controller and export the relevant fields to sysfs.

EDAC MPC85xx DDR3 support is needed if DDR3 memory stick is installed on a
P2020DS board so that EDAC core can recognize DDR3 memory type.
