Subject: [PATCH v8 6/6] ARM: dts: imx6: RIoTboard provide standby on power
off option

This board, as well as some other boards with i.MX6 and a PMIC, uses a
"PMIC_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.
