clk: Document __clk_mux_determine_rate() 



It had some documentation, but not kerneldoc style so it wasn't getting
picked up. Add some docs so scripts can pick this function out.

 * __clk_mux_determine_rate - clk_ops::determine_rate implementation for a mux type clk

 * @hw: mux type clk to determine rate on

 * @req: rate request, also used to return preferred parent and frequencies

 *

 * Helper for finding best parent to provide a given frequency. This can be used

 * directly as a determine_rate callback (e.g. for a mux), or from a more

 * complex clock that may combine a mux with other operations.

 *

 * Returns: 0 on success, -EERROR value on error
