powerpc/cell: Add missing of_node_put()s in cbe_regs.c

There are several bugs as following:

(1) In cbe_get_be_node(), hold the reference returned by of_find_xxx and
    of_get_xxx OF APIs and use it to call of_node_put().
(2) In cbe_fill_regs_map(), same as above.
(3) In cbe_regs_init(), during the iteration of for_each_node_by_type(),
    the refcount of 'cpu' will be automatically increased and decreased.
    However, there is a reference escaped out into 'map->cpu_node' and
    it should be properly handled.
