Series clk: Make determine_rate mandatory for muxes | expand

The lan966x driver registers a gck clock with both a determine_rate and
a round_rate implementation. Both are equivalent, and are only called by
clk_core_determine_round_nolock() which favors determine_rate.

Thus, lan966x_gck_round_rate() is never called, so we can just remove
it.
