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 V4 1/2] scsi: ufs: Add support for sending NOP OUT UPIU [PATCH V4 2/2] scsi: ufs: Set fDeviceInit flag to initiate device initialization Changes from v3: - Addressed some of the comments by Seungwon Jeon on runtime PM. 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.
