Subject: [PATCH v3 04/12] platform/x86: intel_menlow: switch to use <linux/units.h> helpers

This switches the intel_menlow driver to use deci_kelvin_to_celsius() and
celsius_to_deci_kelvin() in <linux/units.h> instead of helpers in
<linux/thermal.h>.

This is preparation for centralizing the kelvin to/from Celsius conversion
helpers in <linux/units.h>.

This also removes a trailing space, while we're at it.
