Please stop wrapping regmap APIs. Just use them directly.

We should simply clamp the rate here. It doesn't matter what 'rate' is
when this function is called. The callback is supposed to determine what
the clk rate will be if a consumer called clk_set_rate() with 'rate'.
Don't fail that if the rate is requested to be larger than max, just
tell clk_round_rate() that if you ask for something larger you'll get
PLL_MAX_FREQ.
