[PATCH v3 1/4] edac: Add an function to retrieve the EDAC debugfs node

Hi Borislav,

quoted

EXPORT_SYMBOL_GPL() if it is going to be used by modules.

Better yet, move it to the header.

I can't move it completely to the header and make it static. It will
generate a lot of compiler warning as it isn't used by other modules.
I will add EXPORT_SYMBOL_GPL() in the next version.
