The changes in this patch are for multifunction cards insertions/removals
and  bug fixes:

1. fix up new nodes' linux_phandle field.
2. new nodes' phb, devfn(and so on) need to be fixed even the nodes don't
	have "interrupts".
3. change of_remove_node to non-recurisve func. The recursions will be done
	by the caller.
4. add a new function -- of_finish_dynamic_node_interrupts()
