[ Upstream commit c4a7b9b587ca1bb4678d48d8be7132492b23a81c ]
When thermnal zones are defined, trip points definitions are mandatory.
Define a couple of critical trip points for monitoring of existing
PMIC and SOC thermal zones.
This was lost between txt to yaml conversion and was re-enforced recently
via the commit 8c596324232d ("dt-bindings: thermal: Fix missing required property")
