There are several helper macros to convert kelvin to/from Celsius in
<linux/thermal.h> for thermal drivers.  These are useful for any other
drivers or subsystems, but it's odd to include <linux/thermal.h> just for
the helpers.

This adds a new <linux/units.h> that provides the equivalent inline
functions for any drivers or subsystems, and switches all the users of
conversion helpers in <linux/thermal.h> to use <linux/units.h>
helpers.

* v3
- rename new header name from <linux/temperature.h> to <linux/units.h>
- add milli_kelvin_to_millicelsius() and millicelsius_to_milli_kelvin() and
  use them for implementing other helpers
- add MILLIDEGREE_PER_DEGREE and MILLIDEGREE_PER_DECIDEGREE and replace
  the hardcoded constants
- add kelvin_to_celsius() and celsius_to_kelvin() in <linux/units.h>
- add Reviewed-by tags
- switch iwlegacy driver to use <linux/units.h> helpers
- switch iwlwifi driver to use <linux/units.h> helpers
- remove unused TO_MCELSIUS macro in armada thermal driver
- switch qcom-vadc-common module to use <linux/units.h> helpers

* v2
- add deci_kelvin_to_millicelsius_with_offset() in linux/temperature.h
- stop including linux/temperature.h from linux/thermal.h
- include <linux/temperature.h> explicitly from thermal drivers
- fix s/temprature/temperature/ typo in commit log
- use deci_kelvin_to_millicelsius_with_offset() in ACPI thermal zone driver
- don't mix up another fix (format string for cellsius value)
- add Acked-by and Reviewed-by tags

Akinobu Mita (12):
  add helpers for kelvin to/from Celsius conversion
  ACPI: thermal: switch to use <linux/units.h> helpers
  platform/x86: asus-wmi: switch to use <linux/units.h> helpers
  platform/x86: intel_menlow: switch to use <linux/units.h> helpers
  thermal: int340x: switch to use <linux/units.h> helpers
  thermal: intel_pch: switch to use <linux/units.h> helpers
  nvme: hwmon: switch to use <linux/units.h> helpers
  thermal: remove kelvin to/from Celsius conversion helpers from
    <linux/thermal.h>
  wireless: iwlegacy: use <linux/units.h> helpers
  wireless: iwlwifi: use <linux/units.h> helpers
  thermal: armada: remove unused TO_MCELSIUS macro
  iio: adc: qcom-vadc-common: use <linux/units.h> helpers
