    uart: only use MSI on devices that advertise 1 MSI vector

    This updates r311987/fb1d9b7f4113d which allowed any number of vectors to
be
    used. Since we're just attaching one instance, the meaning of more than one
    vector is not clear and seems to cause problems. Fall back to old methods
for
    these cards.
