clk: mediatek: mt2701-aud: fix conversion to mtk_clk_simple_probe

Some of the audio subsystem clocks defined in clk-mt2701.h aren't
actually used by the driver. This broke conversion to
mtk_clk_simple_probe which expects that the highest possible clk id is
defined by the ARRAY_SIZE.

Add additional dummy clocks to fill the gaps and remain compatible with
the existing DT bindings.
