Subject: [PATCH V2 0/3] ufs: ufs-qcom: Add support firmware managed platforms

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
