[PATCH] arm64: dts: qcom: monaco-arduino-monza: Add sleep button

[Loic Poulain]

Add the board's horizontal button connected to GPIO69 as a gpio-keys input.
The button generates KEY_SLEEP events and is configured as a wakeup source.

Note: The button is actually connected to the onboard MCU, and forwarded
to the SoC via an active-high GPIO.
