    [POWERPC] Fix legacy serial search for opb bus ports
    The patch to legacy_serial.c (1a7507c7da2df6856e085e0fbb0c9ea8c12ac4e,
    Reduce code duplication in legacy_serial, add UART parent types) changed
    the semantics for opb ports from type = "opb" || compatible = "ibm,opb"
    to type = "opb" && compatible = "ibm,opb".
    The result is serial ports on our QS21s (Cell blades) don't get found,
    and for some reason the machine doesn't boot at all - possibly it's
    panicking due to lack of a console?
    The fix is to add two entries to the of_device_id table, one that looks
    for type = "opb" and the other compatible = "ibm,opb".
