Hallo Andrew,
I need your ACK or NACK for this patch.

This function is used to configure external PMIC to interpret
signal which will be triggered by pm_power_off as power off.
Since same signal can be used for stand by, I linked PMIC configuration
with pm_power_off_prepare to avoid possible conflicts.

Export pm_power_off_prepare. It is needed to implement power off on
Freescale/NXP iMX6 based boards with external power management
integrated circuit (PMIC).
