Rob Herring 408d808893 EDAC: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it was merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

when irq_dispose_mapping() is called. Instead of calling

York Sun 4e2c3252d2 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.
