EDAC, fsl_ddr: Add missing DDR DRAM types
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.
