    [LINUX] 3.14: apf28: add pm_power_off function
    
    When shutting down the board with the poweroff command, an halt is
    actually performed because there is no pm_power_off function defined.
    The SoC is then stuck in an infinite loop.
    
    This patch adds a pm_power_off function to shut down the SoC.
