[RFC PATCH v2 1/3] dt-bindings: power: sequencing: qcom-wcn: document wakeup-source

[Linghui Wu <linghui.wu@oss.qualcomm.com>]

The SW_CTRL GPIO can be used as a wake signal on platforms where the WCN
device must wake the application processor.

Document wakeup-source and require the existing swctrl-gpios property
when it is present.
