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/20230908145329.154024-2-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)

v1 -> v2:
1. Removed 2 changes which were exposing power info in sysfs
2. Removed 1 change which was moving data structs to phy-qcom-qmp-ufs.h
3. Added one new change (the 1st one) to clean up usage of ufs_dev_params based on comments from Mani
4. Adjusted the logic of UFS device version detection according to comments from Mani:
4.1 For HW version < 0x5, go through dual init
4.2 For HW version >= 0x5
a. If UFS device version is populated, one init is required
b. If UFS device version is not populated, go through dual init

Bao D. Nguyen (1):
scsi: ufs: ufs-qcom: Add support for UFS device version detection

Can Guo (6):
scsi: ufs: host: Rename structure ufs_dev_params to ufs_host_params
scsi: ufs: ufs-qcom: Setup host power mode during init
scsi: ufs: ufs-qcom: Allow the first init start with the maximum
supported gear
scsi: ufs: ufs-qcom: Limit HS-G5 Rate-A to hosts with HW version 5
scsi: ufs: ufs-qcom: Set initial PHY gear to max HS gear for HW ver 5
and newer
phy: qualcomm: phy-qcom-qmp-ufs: Add High Speed Gear 5 support for
SM8550
