The same change should be applied for M3-N and RZ/G2M, right?

R-Car E3 and RZ/G2E already use the extended register set, as they do not
have the basic set.

For SoCs having both, this feels a bit like describing software policy, instead
of hardware, to me. Would it make sense to extend the audio bindings, and
allow describing both the basic and extended register sets, and let the driver
make the decision which one to use?
