[PATCH/RESEND V4 00/17] UFS: Power management support

[Dolev Raviv <draviv@codeaurora.org>]

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.

 - 6 new patches apended at the end
 - Allow overriding power configuration with controller support and
   preferences/capabilities <Dolev Raviv>
