clk: gpio: Really allow an optional clock= DT property
We mis-merged the original patch from Russell here and so the patch went almost all the way, except that we still failed to probe when there wasn't a clocks property in the DT node. Allow that case by making a negative value from of_clk_get_parent_count() into "no parents", like the original patch did.
