While we try to transition from a separate ufs phy driver to a
more integrated qmp phy driver, don't let SCSI_UFS_QCOM to
enable PHY_QCOM_UFS config by default.
The users should enable this in their defconfigs.
Also add inline definitions for couple of functions -
a) ufs_qcom_phy_set_tx_lane_enable()
b) void ufs_qcom_phy_save_controller_version()
to enable clean build for SCSI_UFS_QCOM.

This selects the QCOM specific additions to UFSHCD platform driver.
