The 'thermal-zones' node with the SoC thermal zones is usually created
in the <soc>.dtsi, however it doesn't exist yet. The 'Add DT bindings
and device tree nodes for TSENS in SC7280' series
(https://patchwork.kernel.org/project/linux-arm-msm/list/?series=478225)
is creating it, but the series hasn't landed yet.

The node is needed by other patches in this series that add non-SoC
thermal zones. Hence either an empty node needs to be added (for now)
or this series should 'officially' depend on the TSENS series mentioned
above.

You can reference the TZ node as /thermal-zones/ even from non-SoC 
includes. See pm8150.dtsi for example.

I will add the dependency in cover letter and drop this patch.
