ARM: imx6: disable the GIC CPU interface before calling stby-poweroff sequence

Browse Source 
[ Upstream commit 783f3db030 ]

Any pending interrupt can prevent entering standby based power off state.
To avoid it, disable the GIC CPU interface.

Fixes: 8148d21360 ("ARM: imx6: register pm_power_off handler if "fsl,pmic-stby-poweroff" is set")
