ARM: dts: r8a7791: Correct critical CPU temperature
commit e4fdf59bcce3b490bbc7197145bcb9f9d5a18cd3 upstream. The R-Car M2W hardware manual states that Tc = –40°C to +105°C. The thermal sensor has an accuracy of ±5°C and there can be a temperature difference of 1 or 2 degrees between Tjmax and the thermal sensor due to the location of the latter. This means that 95°C is a safer value to use.
