    kobject: convert parisc/pdc_stable to kobj_attr interface
    
    This makes the code a bit simpler and and gets us one step closer to
    deleting the deprecated subsys_attr code.
    
    NOTE, this needs the next patch in the series in order to work properly.
    This will build, but the sysfs files will not properly operate.
