That was my thought while I was implementing this. I guess HW
guys had their reasons.

Probably yes. I was never contacted about this PIO driver so
either they fixed it manually and never sent a patch or they are
not using it.

Ah, I reminded now that ARC PGU DRM driver (which is needed for
I2S audio to work) is totally broken in 4.9 because of some DRM
core changes and was never backported because the fix was simply
too large.

Yeah, I think given all these reasons we can drop this patch.
