These are pins for the AFE block, not specific to any machine, so:
1. They should be moved to the AFE driver.
2. Their names should match the underlying interface (I2SOUT4), instead
of the intended use case (ETDMOUT_SPK).
3. Their related routes should be set statically in the AFE driver.
Also, for the I2S interfaces, since there are input and output pins, but
also common clock pins, you should either split out the common clock pins
as a separate pinctrl entry, or just combine them so that you have one
entry for each interface.
Last, you need to document the pinctrl names as required in the binding.
