thermal/drivers/hisi: Simplify the temperature/step computation

Browse source

commit 48880b979c upstream.

The step and the base temperature are fixed values, we can simplify the
computation by converting the base temperature to milli celsius and use a
pre-computed step value. That saves us a lot of mult + div for nothing at
runtime.

Take also the opportunity to change the function names to be consistent with
the rest of the code.
