[PATCH V2 3/4] cpufreq: Export cpufreq_update_pressure

[Sibi Sankar <quic_sibis@quicinc.com>]

The SCMI cpufreq driver doesn't require any additional signal
smoothing provided by arch_update_hw_pressure interface, export
cpufreq_update_pressure so that it can be called upon directly
instead.

v2:
* Export cpufreq_update_pressure and use it directly [Lukasz]
