[PATCH 8/8] thermal: remove kelvin to/from Celsius conversion helpers from <linux/thermal.h>

[Akinobu Mita]

This removes the kelvin to/from Celsius conversion helpers in
<linux/thermal.h> which were switched to <linux/temperature.h> helpers.

DECI_KELVIN_TO_MILLICELSIUS_WITH_OFFSET() is only used by ACPI thermal
zone driver and the usage is specific to the driver.  So this macro
is moved to the ACPI thermal driver rather than generic header.
