platform/x86: asus-wmi: switch to use <linux/units.h> helpers

The asus-wmi driver doesn't implement the thermal device functionality
directly, so including <linux/thermal.h> just for
DECI_KELVIN_TO_CELSIUS() is a bit odd.

This switches the asus-wmi driver to use deci_kelvin_to_millicelsius()
in <linux/units.h>.

The format string is changed from %d to %ld due to function returned
type.
