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 V2:
- 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.

preferences/capabilities <Dolev Raviv>
