[RFC PATCH 3/3] arm64: dts: qcom: shikra: enable WCN SW_CTRL wakeup

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

Configure the WCN power sequencer SW_CTRL signal as a named wake IRQ and
mark it as a wakeup source. The CQM SOM DTSI is shared by the CQM and CQS
EVKs, while the IQS EVK uses the IQS SOM DTSI.
