thermal: gov_step_wise: Clarify cooling logic description comment

The cooling logic description comment next to the get_target_state()
definition is slightly ambiguous in what it means by "lower cooling
state", so clarify that by replacing the ambuguous phrase with "the
minimum applicable cooling state".

No functional impact.
