arm64: dts: qcom: sm8550: 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.

Remove the copypasta-from-downstream userspace governor entries while
at it.
