x86/CPU/AMD: Use default_groups in kobj_type

There are currently 2 ways to create a set of sysfs files for a
kobj_type, through the default_attrs field, and the default_groups
field. Move the AMD mce sysfs code to use default_groups field which has
been the preferred way since

  aa30f47cf666 ("kobject: Add support for default attribute groups to kobj_type")

so that the obsolete default_attrs field can be removed soon.
