Linux kernel .get_temp() callback reports values in millicelsius, U-Boot currently reports them in celsius. Align the two and report in millicelsius. Update drivers accordingly. Update callsites that use thermal_get_temp() as well. The 'temperature' command now reports temperature in millicelsius as well, with additional accuracy. This changes command line ABI slightly.
