arm64: dts: qcom: sc8280xp: Throttle the GPU when overheating
Add an 85C passive trip point with 1C of hysteresis to ensure the
thermal framework takes sufficient action to prevent reaching junction
temperature. Also, add passive polling to ensure more than one
temperature change event is recorded.
