clk: mediatek: mt8365: Join top_misc_mux_gates and top_misc_muxes arrays

In preparation for migrating this driver to the simple probe mechanism,
join the audio gates to the top_misc_mux_gates array of mtk_composite
clocks in one top_misc_muxes array.

While at it, since the `apll_i2s0_parents` array is for all i2s clocks,
rename that to `apll_i2s_parents`.
