279fa58035 EDAC, fsl_ddr: Make locally used symbols static 
Fix the following sparse warnings:

  drivers/edac/fsl_ddr_edac.c:148:1: warning:
   symbol 'dev_attr_inject_data_hi' was not declared. Should it be static?
  drivers/edac/fsl_ddr_edac.c:150:1: warning:
   symbol 'dev_attr_inject_data_lo' was not declared. Should it be static?
  drivers/edac/fsl_ddr_edac.c:152:1: warning:
   symbol 'dev_attr_inject_ctrl' was not declared. Should it be static?

78d88e8a3d edac: rename edac_core.h to edac_mc.h 
Now, all left at edac_core.h are at drivers/edac/edac_mc.c,
so rename it to edac_mc.h.

55764ed37e EDAC, fsl_ddr: Fix IRQ dispose warning when module is removed 
When compiled as a module, removing it causes kernel warnings
when irq_dispose_mapping() is called. Instead of calling
irq_of_parse_and_map(), use platform_get_irq() to acquire the IRQ
number.

Get endianness from device tree. Both big endian and little endian are
supported. Default to big endian for backwards compatibility to MPC85xx.

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.

Carve out the DDR part from the mpc85xx EDAC driver in preparation to
