These clock gates provide input clocks for ACM. They can be selected by
IMX_ADMA_ACM_* macros. As SAI driver does not provide Tx/Rx bitclock
clocks yet, add dummy clocks for the unimplemented inputs.

ACM needs a lot of input clocks, while currently only 4 (aud_rec*_lpcg and
aud_pll_div*_lpcg) do have an actual clock provider. For each unsupported
clock there is a 0Hz fixed-clock added. This should be removed once a proper
clock provider is added.
This is different to the clock-dummy in imx8qxp.dtsi which provides a dummy
clock for an invalid mux settings.
