ARM: dts: r8a7793: Correct critical CPU temperature
The R-Car M2N 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.
