The compatible DDR controllers may support DDR, DDR2, DDR3, DDR4 DRAM.
An individual controller doesn't support all of them. The EDAC driver
reads SDRAM_CFG to determine which mode is configured.
Add DDR4 and drop the defines used only in the mtype assignment.

The mpc85xx-compatible DDR controllers are used on ARM-based SoCs too.
Carve out the DDR part from the mpc85xx EDAC driver in preparation to
support both architectures.
