Subject: [PATCH v4 15/23] clk: mediatek: mt8192: Join top_adj_divs and top_muxes

These two are both mtk_composite arrays, one dependent on another, but
that's something that the clock framework is supposed to sort out and
anyway registering them separately isn't going to ease the framework's
job in checking dependencies.

Put the contents of top_adj_divs in top_muxes to join them together
and register them in one shot.
