This patch series enables Multi-Circular Queue (MCQ) support for the UFS host controller on Qualcomm SM8650 and SM8750 platforms. MCQ is a modern queuing model that improves performance and scalability by allowing multiple hardware queues. Patch 1 updates the device tree bindings to allow the additional register regions and reg-names required for MCQ operation. Patches 2 and 3 update the device trees for SM8650 and SM8750 respectively to enable MCQ by adding the necessary register mappings and MSI parent. Patch 4 is streamlining UFS MCQ resource mapping with a single MCQ region mapping. Tested on SM8650 and SM8750. Changes from v1: 1. As per Krzysztof's suggestion, replaced mcq_vs and mcq_sqd DT mappings with a single MCQ region mapping. 2. Minor changes in commit messge as per Krzysztof's suggestion.
