The original code tries to determine which serial device has been
initialized as console early at initarm, but it fails to so because it
was created with a different bus_space_tag and iobase. I was able to
workaround the iobase, but wasn't able to create a "equal" (in terms
of satisfying "bus_space_is_equal") bus_space_tag in a sane way, so I
decided to take a simpler road: assume the first serial device is the
console.
