EDAC: Initialize EDAC features sysfs attributes

Browse Source 
Fix the lockdep splat caused by missing sysfs_attr_init() calls for the
recently added EDAC feature's sysfs attributes.

In lockdep_init_map_type(), the check for the lock-class key if
(!static_obj(key) && !is_dynamic_key(key)) causes the splat.

  Backtrace:
