Subject: [PATCH v1 5/5] ARM: dts: imx6: RIoTboard provide Standby to PowerOff option

This board, as well as some other boards with i.MX6 and a PMIC, uses a
"MPIC_STBY_REQ" line to notify the PMIC about a state change.
The PMIC is programmed for a specific state change before triggering the
line.
In this case, PMIC_STBY_REQ can be used for Stand by, Sleep
and Power off modes.
