[PATCH V4 0/4] ufs: ufs-qcom: Add support firmware managed platforms

[Ram Kumar Dwivedi <ram.dwivedi@oss.qualcomm.com>]

On Qualcomm automotive SoC SA8255P, platform resource like clocks,
interconnect, resets, regulators and PHY are configured remotely by
firmware.

Logical power domain is used to abstract these resources in firmware
and SCMI power protocol is used to request resource operations by using
runtime PM framework APIs such as pm_runtime_get/put_sync to invoke
power_on/_off calls from kernel respectively.

Changes from V1
1. Updated "dma-coherent" property type from boolean to just true.
2. Switched from QUIC mail ID to OSS mail ID. 
3. Added Acknowledged by tag from Dmitry for patch 1/3 
4. Added Reviewed-by tag from Manivannan for patch 1/3 

Changes from V2
1. Added new patch "scsi: ufs: core Enforce minimum pm level for sysfs
   configuration" to prevent users from selecting unsupported power
   levels via sysfs.
2. Set minimum power level (UFS_PM_LVL_5) for SA8255P platforms.
3. Changed DT example in qcom,sa8255p-ufshc.yaml to use single-cell
   addressing instead of dual-cell addressing.

Changes from V3
1. Removed address-cells and size-cells from example DT in
   qcom,sa8255p-ufshc.yaml.
