the atmel_ports is link to the console number and not the device id
this was not detected on at91 as we always register the dbgu on the console
as ttyS0
tested on at91sam9263 by setting the dbgu as ttyS1 and use as console

* 'tty-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty-2.6:
tty: update MAINTAINERS file due to driver movement
tty: move drivers/serial/ to drivers/tty/serial/
tty: move hvc drivers to drivers/tty/hvc/
|

The serial drivers are really just tty drivers, so move them to
drivers/tty/ to make things a bit neater overall.
This is part of the tty/serial driver movement proceedure as proposed by
Arnd Bergmann and approved by everyone involved a number of months ago.
