Maybe sc7280-audioreach.dtsi containing all these changes that could be
reused by others would be in order?

Surely they shouldn't cause issues, even if the vote would be
superfluous? They are still powered by these power domains, I'd assume?

The drivers use clk_get with name-based lookup.. you should be able to
simply extend the list in the common DTSI. Please test that on both
audioreach and the other thing though.
