scsi: ufs-qcom: enable UFSHCD_QUIRK_BROKEN_UFS_HCI_VERSION
Newer revisions of QUALCOMM Technologies UFS host controller may not advertise the correct version information in UFS HCI VER register. To handle this, enable UFSHCD_QUIRK_BROKEN_UFS_HCI_VERSION to let UFS standard host controller driver call into vendor specific operation to get right UFS HCI VER register value.
