[ Upstream commit 4de95950d970c71a9e82a24573bb7a44fd95baa1 ]

The Snapdragon 670 has the same quirk as Snapdragon 845 (needing to
restore the dll config). Add a compatible string check to detect the need
for this.

Supporting device trees which are invalid under 6.0 schema? It's not a bug fix,
it's a feature.

I'm new to this, so I apologize if I don't understand stable kernel development.

Does this not enable hardware to work properly? We take quirks/device
enablement into stable tree as well.

It does, given that there are no device tree dependency issues. Thanks for the
clarification.
