[PATCH V2 3/5] arm64: dts: imx8qxp: Add scu power key node

[Anson Huang <Anson.Huang@nxp.com>]

Add scu power key node for i.MX8QXP, disabled by default as it
depends on board design.

Signed-off-by: Anson Huang <Anson.Huang@nxp.com>

Changes since V1:
	- remove "wakeup-source" property, as it is NOT needed for scu mu interrupt;
