[PATCH 1/2] arm64: dts: imx8mn-bsh-smm-s2/pro: Adjust CPU thermal trip points

[Kaiwen Zhang]

Hardware thermal qualification of the BSH SMM S2/pro board shows that
the existing CPU thermal trip points trigger throttling too early
during peak operation.

Raise the passive trip temperature from 85 to 101 degrees Celsius
and its hysteresis from 2 to 9 degrees Celsius. Raise the critical
trip temperature from 95 to 107 degrees Celsius to match the
qualified thermal limits.
