changes since v1: Addressed comments by Krzysztof
- expanded the acronym WCSS
- added 'maxItems' to property 'firmware-name'
- renamed sleep clock name 'im_sleep' to 'sleep'
- reordered items of property 'qcom,smem-states' keeping 'stop'
first. Addressed the same in example and in dtsi files.
- ordered required properties in the same order as property description
- dropped unused label 'q6v5_wcss' in example dts
