This series enables HS-G5 support on SM8550.

This series is rebased on below changes from Mani -

https://patchwork.kernel.org/project/linux-scsi/patch/20230908145329.154024-1-manivannan.sadhasivam@linaro.org/
https://patchwork.kernel.org/project/linux-scsi/patch/20230908145329.154024-2-manivannan.sadhasivam@linaro.org/

This series is tested on below HW combinations -

SM8550 MTP + UFS4.0
SM8550 QRD + UFS3.1
SM8450 MTP + UFS3.1 (for regression test)
SM8350 MTP + UFS3.1 (for regression test)

Note that during reboot test on above platforms, I occasinally hit
PA (PHY) error during the 2nd init, this is not related with this
series. A fix for this is mentioned in below patchwork -

Also note that on platforms, which have two sets of UFS PHY settings
are provided (say G4 and no-G4, G5 and no-G5). The two sets of PHY
settings are basically programming different values to different
registers, mixing the two sets and/or overwriting one set with another
set is definitely not blessed by UFS PHY designers. For SM8550, this
series will make sure we honor the rule. However, for old targets Mani
and I will fix them in another series in future.
