arm64: dts: qcom: sm8650: setup gpu thermal with higher temperatures

Browse Source 
[ Upstream commit 2250f65b32565eb8b757e89248c75977f370f498 ]

On the SM8650, the dynamic clock and voltage scaling (DCVS) for the GPU
is done from the HLOS, but the GPU can achieve a much higher temperature
before failing according the reference downstream implementation.

Set higher temperatures in the GPU trip points corresponding to
the temperatures provided by Qualcomm in the dowstream source, much
closer to the junction temperature and with a higher critical
temperature trip in the case the HLOS DCVS cannot handle the
temperature surge.

The tsens MAX_THRESHOLD is set to 120C on those platforms, so set
the hot to 110C to leave a chance to HLOS to react and critical to
115C to avoid the monitor thermal shutdown.
