[PATCH V3] workaround for mpc52xx erratum #364 (serial may not be reset in break state)

[René Bürgel]

Hey, folks

This is v3 of my patch to work around erratum #364 of the MPC5200(B). I 
removed most "magic" looking numbers, documenting the rest. As mentioned 
before, the previous patches weren't working for low baudrates (<9600). 
This should be fixed now.

But there's still one thing, that bothers me a bit - if there is REALLY 
a break on the line, closing the driver may take until it's gone. I 
don't know whether this is really satisfying, but i think it's better 
than the alternative: no serial connection until the next reboot.
