[PATCH v2] Add i.MX23/28 auart support

[Sascha Hauer]

This is the second version of these patches. I have reworked the driver to
support the NPCK, BRKINT, PARMRK, IGNPAR, IGNBRK and cflag CREAD flags. I have
tested these flags to the best of my knowledge, but it's sometimes hard to
judge if the behaviour is expected.
