EDAC: Export edac sysfs class to users.
Move toplevel sysfs class to the stub and make it available to non-modularized code too. Add proper refcounting of its users and move the registration functionality into the reference counting routines. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
