It seems none of these modes are supported yet. aic32x4_hw_params setups

Otherwise hw_params fails. So currently mclk is not optional for the
driver. But it is still optional for the real hardware.

What do you think about declaring the mclk as optional property in the
DT bindings documentation but to handle it as a required clock in the
driver?

That's fine, makes sense.
