There is an issue:
SDMA3 can't work without setting AUDIOMIX_CLKEN0[SDMA2] (bit-26) to 1

The workaround is:
As the reset state of AUDIOMIX_CLKEN0[SDMA2] is enabled,
we just need to keep it on as reset state, don't touch it
in kernel, then every thing is same as before, if we register
the clock in clk-audiomix, then kernel will try to disable
it in idle.

Fixes tag, given that this is fixing an issue?
