EDAC: Add support for EDAC device features control
Add generic EDAC device feature controls supporting the registration of RAS
features available in the system. The driver exposes control attributes for
these features to userspace in
/sys/bus/edac/devices/<dev-name>/<ras-feature>
[ bp: Touch-up documentation, simplify, make edac_dev_type static,
fixup edac_dev_register() retvals. ]
