    pcengines/apu1: Enable USB overcurrent detection.
    
    The two external USB ports and the internal USB header have overcurrent
    protection chips with the low-active overcurrent signal connected to the
    chipset.
    
    The power-on default for this register disables the software detection
    of overcurrent conditions.
    
    After setting the register Linux correctly shows the overcurrent
    condition in the kernel log (tested by shorting the 5v and gnd lines on
    J14 / the internal USB header):
    [ 2015.229921] usb usb1-port3: over-current condition
    [ 2015.449925] usb usb1-port4: over-current condition
    
    Simlar for the external ports:
    [  256.237916] usb usb1-port1: over-current condition
    [  256.458084] usb usb1-port5: over-current condition
    
    Note that each signal is shared between two ports:
    usboc0#: External ports (port1/5)
    usboc1#: Internal ports (port3/4)
