Thanks for your review. I think my commit message did not explain the
reason clearly enough.

The RubikPi3 compatible is intended to select board-specific machine
driver data from the sc8280xp OF match table (added in patch 4/5 of
this series). RubikPi3 needs different configuration from the existing
QCM6490/QCS6490 sound cards, including the ES8316 MI2S codec clocking
and headset jack setup, so using an existing compatible as a fallback
would select the wrong machine data.
