[PATCH 2/6] clk: Provide a dummy clk_unregister()

Even though unregistration is not actually supported by the clk API it is
still useful to provide a clk_unregister() so that drivers can implement
their unregistration code. This saves having to go back later and update
them once unregistration is possible.
