My suggestion is that instead of doing either of these things it'd be
quicker and less error prone to just fix the core to provide the default
implementation if nothing more specific is provided. Any issues that
causes would already be present with your current series.

The series does fill in __clk_mux_determine_rate for everything though -
if it was just assumed by default the only thing that'd be needed would
be adding the flag.
