Fix temperature for new power kernels

New power kernels (> v46) report the temperature in the format 386 (for
38.6 °C). We need to divide the value from the kernel by 10 in order to
display the correct temperature again.

Note: this breaks temperature reporting for older power kernels.

Thanks to misiak for pointing this out and providing a fix.
