This patch seies introduces support for power management in the driver as well as vendor specific initialization - registers, clocks, voltage regulators etc.
It includes also a rework for the init sequence and other PM pre-requisite such as write protection support, handling well-known LUN, error handling (retries), bkops, START_STOP unit command, and ICC levels settings.

Changes from V5:
- Add a print to "[01/18] scsi: fixing the "type" for well known LUs"
indicating on the type change.
- Moved "sdev->is_visible" test to scsi_sysfs_add_devices
- Reverted the squashed between
"[10/17] scsi: ufs: introduce well known logical unit in ufs" and
"[09/17] scsi: ufs: manually add well known logical"
and addressed othe comments by Chris.
- Fixed a bug and comments reported by Akinobu Mita <akinobu.mita@xxxxxxxxx>
Changes from V4:
- Restored "[01/16] scsi: support well known logical units" to fix type issue"
and renamed "[01/17] scsi: fixing the "type" for well known LUs"
- Add "[02/17] scsi: sysfs: don't add scsi_device if its already added"
to help addressing Chris comments.
- Squashed "[10/17] scsi: ufs: introduce well known logical unit in ufs" and
"[09/17] scsi: ufs: manually add well known logical" and addressed most of
Chris comments here.
- Cleanup in "[11/16] scsi: ufs: add UFS power management support" to align
it with comments made on previous patches.
Changes from V3:
- Replaced "[01/16] scsi: support well known logical units" with
"[09/17] scsi: ufs: manually add well known logical
- add patch "[PATCH V4 05/17] scsi: ufs: add voting support for host"
- Fix couple of compilation issues introduced in V3
- Add a NULL pointer test to hba->vops before accessing it
- Changed disable/enable irq with request/free irq
Changes from V2:
- Reordered scsi core patches
- add patch "[PATCH V3 02/16] scsi: balance out autopm get/put calls in"
- Minor changes/fixes to the patches:
* "[PATCH V3 10/16] scsi: ufs: add UFS power management support"
* "[PATCH V3 12/16] scsi: ufs: Add support for clock gating"
* "[PATCH V3 16/16] scsi: ufs: definitions for phy interface"
In order to address community concerns, and as a result of further
development and testing.
