[PATCH] EDAC: disable sysfs interface

Browse source 
- Disable the EDAC sysfs code.  The sysfs interface that EDAC presents to
  user space needs more thought, and is likely to change substantially.
  Therefore disable it for now so users don't start depending on it in its
  current form.

- Disable the default behavior of calling panic() when an uncorrectible
  error is detected (since for now, there is no sysfs interface that allows
  the user to configure this behavior).
