Some NM PLLs doesn't work well when their output clock rate is set below
certain rate.

Add support for that constrain.

In such a case, you should round the rate to the minimum the clock can
operate at, and not return an error.

That's true for round_rate. But what's the expected behavior of set_rate?
AFAIK we presume all users call round_rate before set_rate, but that doesn't
seem to be true all the time.
