scsi/ufs: qcom: Remove ufs_qcom_phy_*() calls from host
The host makes direct calls into phy using ufs_qcom_phy_*() APIs. These APIs are only defined for 20nm qcom-ufs-qmp phy which is not being used by any architecture as yet. Future architectures too are not going to use 20nm ufs phy. So remove these ufs_qcom_phy_*() calls from host to let further change declare the 20nm phy as broken. Also remove couple of stale enum defines for ufs phy. Signed-off-by: Vivek Gautam <vivek.gautam@codeaurora.org> Acked-by: Martin K. Petersen <martin.petersen@oracle.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
