Merge patch series "Support Multi-frequency scale for UFS"

Merge patch series "Support Multi-frequency scale for UFS"

Ziqi Chen <quic_ziqichen@quicinc.com> says:

With OPP V2 enabled, devfreq can scale clocks amongst multiple frequency
plans. However, the gear speed is only toggled between min and max during
clock scaling. Enable multi-level gear scaling by mapping clock frequencies
to gear speeds, so that when devfreq scales clock frequencies we can put
the UFS link at the appropraite gear speeds accordingly.

This series has been tested on below platforms -
sm8550 mtp + UFS3.1
SM8650 MTP + UFS3.1
SM8750 MTP + UFS4.0
