EDAC: Cleanup atomic_scrub mess
So first of all, this atomic_scrub() function's naming is bad. It looks like an atomic_t helper. Change it to edac_atomic_scrub(). The bigger problem is that this function is arch-specific and every new arch which doesn't necessarily need that functionality still needs to define it, otherwise EDAC doesn't compile. So instead of doing that and including arch-specific headers, have each arch define an EDAC_ATOMIC_SCRUB symbol which can be used in edac_mc.c for ifdeffery. Much cleaner. And we already are doing this with another symbol - EDAC_SUPPORT. This is also much cleaner than having CONFIG_EDAC enumerate all the arches which need/have EDAC support and drivers. This way I can kill the useless edac.h header in tile too.

EDAC is designed to report errors in the core system.
These are low-level errors that are reported in the CPU or
