[PATCH v2 3/5] thermal/cpufreq: Remove arch_update_thermal_pressure()

[Vincent Guittot]

arch_update_thermal_pressure() aims to update fast changing signal which
should be averaged using PELT filtering before being provided to the
scheduler which can't make smart use of fast changing signal.
cpufreq now provides the maximum freq_qos pressure on the capacity to the
scheduler, which includes cpufreq cooling device. Remove the call to
arch_update_thermal_pressure() in cpufreq cooling device as this is
handled by cpufreq_get_pressure().
