[PATCH V4 01/11] scsi: ufs: qcom: add a new phy calibrate API call

[Nitin Rawat]

Introduce a new phy calibrate API call in the UFS Qualcomm driver to
separate phy calibration from phy power-on. This change is a precursor
to the next patchset in this series, which requires these two operations
to be distinct.
