Current of_serial driver assumes unknown serial port to be 8250. But
this behavior may cause fatal problems when the serial port is not
8250. This patch corrects probe routine to ignore unknown serial port.

Is this a bugfix that needs to go in 2.6.22?

This potentially breaks lots of other platforms, so no
please, put it in early in the next cycle and give those
others time to recover from this change.
