    ACPI: Implement power button on !x86
    
    ACPI sleep states are only implemented on x86 systems, so having the
    ACPI power button attempt to enter "S5" (or other state as configured
    via the hw.acpi.power_button_state sysctl) is not useful.
    
    On non-x86 systems, implement the power button with a call to
        shutdown_nice(RB_POWEROFF)
    to shut down the system.
