On SoundWire v2.0+ hardware, some controllers bank the interrupt, FIFO, and status registers in EE-specific windows separated by a stride of 0x1000. Typically, the driver assumes EE1, but platforms like Shikra have the controller routed on EE0. To support platforms with varying EEs, we: 1. Introduce the `qcom,swr-master-ee-val` DT property to configure the target execution environment. 2. Add remapping logic to adjust the register layout offsets by the EE window stride on v2.0+ hardware. The first patch adds DT binding documentation for the new property, and the second implements the EE-aware layout selection in the soundwire driver.
