[PATCH v6 05/12] clk: Use clamp instead of open-coding our own

[Stephen Boyd]

Quoting Maxime Ripard (2022-02-23 02:55:53)
> The code in clk_set_rate_range() will, if the current rate is outside of
> the new range, will force it to the minimum or maximum.

s/will//

> Since it's running under the condition that the rate is either lower
