    powerpc/pseries/vas: 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 pseries vas sysfs code to use default_groups field
    which has been the preferred way since aa30f47 ("kobject: Add
    support for default attribute groups to kobj_type") so that we can soon
    get rid of the obsolete default_attrs field.
