[PATCH 2/4] scsi: ufs: Add UIC DEBUGSAVECONFIGTIME attribute and its field masks

[Kartik Rajput]

Add the UniPro vendor-specific save-config-time attribute and masks for
the two fields within it:

  VS_DEBUGSAVECONFIGTIME       Save-config-time attribute (0xD0A0)
  VS_DEBUGSAVECONFIGTIME_TREF  Field masks within that attribute, for
  VS_DEBUGSAVECONFIGTIME_SCT   use with FIELD_PREP()

ufs-hisi already writes this attribute by its literal address, so name
it in the shared header rather than in the driver. Add it here in
preparation for the Tegra264 UFS host controller driver, which also
programs the two fields.
