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 powerpc opal dump and elog sysfs code to use
default_groups field which has been the preferred way since aa30f47cf6
("kobject: Add support for default attribute groups to kobj_type") so
that we can soon get rid of the obsolete default_attrs field.
