arm64: dts: qcom: sm8650: Throttle the GPU when overheating 



Add an 85C passive trip point to ensure the thermal framework takes
sufficient action to prevent reaching junction temperature and a
110C critical point to help avoid hw damage.

Also, register the GPU as a cooling device and hook it up to the
right thermal zones.
