[RFC PATCH v2 3/3] arm64: dts: qcom: shikra: enable WCN SW_CTRL wakeup

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

The WCN3988 SW_CTRL signal can wake the application processor on the
Shikra CQM, CQS and IQS EVKs.

Mark the WCN power sequencer as a wakeup source so the driver uses the
existing SW_CTRL GPIO as a dedicated wake IRQ.
