EDAC: Allow to pass driver-specific attribute groups
Add edac_mc_add_mc_with_groups() for initializing the mem_ctl_info object with the optional attribute groups. This allows drivers to pass additional sysfs entries without manual (and racy) device_create_file() and co calls. edac_mc_add_mc() is kept as is, just calling edac_mc_add_with_groups() with NULL groups.
