phy: qcom-ufs: add support for QUALCOMM Technologies UFS PHY drivers

This change adds a generic and common API support for ufs phy QUALCOMM
Technologies. This support provides common code and also points
to specific phy callbacks to differentiate between different behaviors
of frequent use-cases (like power on, power off, phy calibration etc).
