From: Brian Norris <briannorris@chromium.org>

commit b5fbaf7d779f5f02b7f75b080e7707222573be2a upstream.

Commit b18c6c3c7768 ("ASoC: rockchip: cdn-dp sound output use spdif")
switched the platform to SPDIF, but we didn't fix up the device tree.

Drop the pinctrl settings, because the 'spdif_bus' pins are either:
* unused (on kevin, bob), so the settings is ~harmless
* used by a different function (on scarlet), which causes probe
failures (!!)

Fixes: b18c6c3c7768 ("ASoC: rockchip: cdn-dp sound output use spdif")
