Subject: [PATCH v1 04/17] ARM: dts: imx6q-apalis: Command pmic to standby for poweroff

From: Max Krummenacher <max.krummenacher@...adex.com>

The Apalis iMX6 HW doesn't allow to use the PWR_ON_REQ signal for
poweroff. Use the fsl,pmic-stby-poweroff property to command the PMIC
into a low power mode in poweroff.
