parisc: remove klist iterators

    driver core: move klist_children into private structure

Broke our parisc build pretty badly because we touch the klists directly
in three cases (AGP, SBA and GSC).  Although GregKH will revert this
patch, there's no reason we should be using the iterators directly, we
can just move to the standard device_for_each_child() API.
