Subject: [PATCH] ALSA: hda/tegra: Re-enable SDO workaround for Tegra194

This workaround was originally added for Tegra194, but no longer gets
applied for it. Commit 615d43540043 ("ALSA: hda/tegra: fix tegra-hda on
tegra30 soc") changed the guard to tegra30-hda, which worked because all
affected archs had the fallback compatible. However, commit 7f0ea5acfc19
("arm64: tegra: Use correct compatible string for Tegra194 HDA") removed
the fallback compatible for Tegra194, causing this to break.

Fixes: 7f0ea5acfc19 ("arm64: tegra: Use correct compatible string for Tegra194 HDA")
