Subject: [PATCH V4 0/2] firmware: arm_scmi: Register and handle limits change notification

This series registers for scmi limits change notifications to determine
the throttled frequency and apply HW pressure.

V4:
* Use EXPORT_SYMBOL_GPL instead. [Trilok]
* Use a interim variable to show the khz calc. [Lukasz]
* Use driver_data to pass on the handle and scmi_dev instead of using
  global variables. Dropped Lukasz's Rb due to adding these minor
  changes.

V3:
* Sanitize range_max received from the notifier. [Pierre]
* Drop patches 1/2 from v2. [Cristian]
* Update commit message in patch 2.

V2:
* Rename opp_xlate -> freq_xlate [Viresh]
* Export cpufreq_update_pressure and use it directly [Lukasz]

Depends on:
HW pressure v6: https://patchwork.kernel.org/project/linux-arm-msm/cover/20240326091616.3696851-1-vincent.guittot@linaro.org/
