powerpc/cacheinfo: use default_groups in kobj_type

Browse source 
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 cacheinfo 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.
