Empty node..? what am i missing here...

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.

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

Thanks,
Satya Priya
