[PATCH v2 2/5] thermal: cpufreq_cooling: Use new thermal pressure update function

From: Lukasz Luba <lukasz.luba@arm.com>
Date: 2021-10-15 14:47:24
Also in: linux-arm-msm, linux-pm, lkml
Subsystem: the rest, thermal, thermal/cpu_cooling · Maintainers: Linus Torvalds, Rafael J. Wysocki, Daniel Lezcano, Amit Daniel Kachhap, Viresh Kumar

Thermal pressure provides a new API, which allows to use CPU frequency
as an argument. That removes the need of local conversion to capacity.
Use this new function and remove old conversion code.
