clk: add clk_determine_rate_noop()

Add a new helper clk_determine_rate_noop() that's for clocks where the
rate rounding is handled by the firmware/hardware, or the clock is
capable of any rate. The requested rate is passed through unchanged,
and the actual rate will be learned via recalc_rate() after the rate
is set.

This shared helper will be used to get rid of the driver-specific empty
determine rate implementations that are present in the tree.
