Subject: [PATCH 1/2] dt-bindings: thermal: qcom-tsens: make ipq5018 tsens
 standalone compatible

From: George Moussalem <george.moussalem@...look.com>

The tsens IP found in the IPQ5018 SoC should not use qcom,tsens-v1 as
fallback since it has no RPM and, as such, must deviate from the
standard v1 init routine as this version of tsens needs to be explicitly
reset and enabled in the driver.

So let's make qcom,ipq5018-tsens a standalone compatible in the bindings.
