arm64: dts: qcom: sc8280xp: Throttle the GPU when overheating
[ Upstream commit f7fd6d04c1046107a87a0fc883ed044cf8b877a1 ]
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.
