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 V3 1/2] scsi: ufs: Add support for sending NOP OUT UPIU
[PATCH V3 2/2] scsi: ufs: Set fDeviceInit flag to initiate device initialization
Changes from v2:
- Enable auto bkops by default explicitly during bootup so that we
may not assume it as enabled after reset.
- Enable runtime PM support for contexts that are not part of SCSI,
so that the host is not suspended while running other contexts
like bkops exception handling.
Changes from v1:
- Minor cleanup and rebase
- Forced enable of auto bkops during initialization to make sure device
and driver state are matched.
