Subject: [PATCH v3 03/20] phy: qcom-qmp-ufs: Move register settings to qmp_phy_cfg_tbls struct
As done for Qcom PCIe PHY driver, let's move the register settings to the
common qmp_phy_cfg_tbls struct. This helps in adding any additional PHY
settings needed for functionalities like HS-G4 in the future by adding one
more instance of the qmp_phy_cfg_tbls.
