As there are now two of us who have been tripped up by this does anyone think 
the untested patch below is

a) worthwhile
b) likely to be acceptable
c) likely to work

It feels wrong to be putting something arch specific in such general code but 
setting it as a default is cleaner than trying to select it from 
ARCH_KIRKWOOD_DT because default respects depends lines.

          If you have a PowerPC based system that has serial ports
          on a platform specific bus, you should enable this option.
