EDAC: Add missing MODULE_DESCRIPTION() macros

With ARCH=arm64

  make allmodconfig && make W=1 C=1

reports:

  WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/edac/layerscape_edac_mod.o

Add the missing invocation of the MODULE_DESCRIPTION() macro to all
files which have a MODULE_LICENSE().

This includes mpc85xx_edac.c and four octeon_edac-*.c files which,
although they did not produce a warning with the arm64 allmodconfig
configuration, may cause this warning with other configurations.
