How?  Any means I can think of would be uglier, more complex, and/or put 
information in the bootwrapper that it shouldn't have.

I think it belongs in the dts, anyway...  The default serial port is 
more a property of the board than a configuration issue (although it has 
aspects of both).  Any bootloader that wants to set a non-default serial 
port is welcome to overwrite the property.
