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 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.
