Add host assisted background operations for UFS device and runtime PM
helpers for ufshcd platform and pci glue drivers. The background operations
are disabled during runtime resume and enabled when the device is idle and
runtime suspended.
These patches depends on:
[PATCH 01/10] scsi: ufs: wrap the i/o access operations
[PATCH 02/10] scsi: ufs: amend interrupt configuration
[PATCH 03/10] scsi: ufs: remove version check before IS reg clear
[PATCH 04/10] scsi: ufs: rework link start-up process
[PATCH 05/10] scsi: ufs: Fix the response UPIU length setting
[PATCH 06/10] scsi: ufs: use devres functions for ufshcd
[PATCH 07/10] ufshcd-pltfrm: add missing empty slot in ufs_of_match[]
[PATCH 08/10] ufs: fix register address in UIC error interrupt handling
[PATCH 09/10] ufshcd-pltfrm: remove unnecessary dma_set_coherent_mask() call
[PATCH 10/10] ufs: fix DMA mask setting
[PATCH V2 1/2] scsi: ufs: Add support for sending NOP OUT UPIU
[PATCH V2 2/2] scsi: ufs: Set fDeviceInit flag to initiate device initialization
Changes from v1:
- Minor cleanup and rebase
- Forced enable of auto bkops during initialization to make sure device
and driver state are matched.
