mpc8xxx: DDR2/DDR3: Clean up DIMM-type switch statements
The numeric constants in the switch statements are replaced by #defines
added to the common ddr_spd.h header. This dramatically improves the
readability of the switch statments.
In addition, a few of the longer lines were cleaned up, and the DDR2
type for an SO-RDIMM module was added to the DDR2 switch statement.
