ARM: dts: imx6: add pm_power_off support for i.mx6 chips
All chips of i.mx6 can be powered off by programming SNVS. For example : On i.mx6q-sabresd board, PMIC_ON_REQ connect with external pmic ON/OFF pin, that will cause the whole PMIC powered off except VSNVS. And system can restart once PMIC_ON_REQ goes high by push POWRER key. Signed-off-by: Robin Gong <b38343@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
