dt-bindings: soundwire: qcom: add qcom,swr-master-ee-val property

Add documentation for the qcom,swr-master-ee-val Device Tree property
used by Qualcomm SoundWire masters to describe the execution-environment
value for interrupt routing.

This property allows platform DTs to specify the EE value used to direct
SoundWire master interrupts to the appropriate CPU target.
