clk: sunxi-ng: ccu_nm: convert from round_rate() to determine_rate()

The round_rate() clk ops is deprecated, so migrate this driver from
round_rate() to determine_rate() using the Coccinelle semantic patch
on the cover letter of this series.

I manually fixed up one minor formatting issue that occurred after
applying the semantic patch:

        req->rate = ccu_nm_find_best(&nm->common, req->best_parent_rate,
                                     req->rate,
                                     &_nm);

I manually changed it to:

        req->rate = ccu_nm_find_best(&nm->common, req->best_parent_rate,
                                     req->rate, &_nm);
