description:
Check for "ssp-console" and "ssp-control" properties.
If we find them, set the baud rate to 115200.
This allows the RSC to be the console on an E250:

  sab1 at ebus0 addr 200000-20007f ipl 35: rev 3.2
  sabtty2 at sab1 port 0: console i/o
  sabtty3 at sab1 port 1

XXX; We should really check the baud rate properties and use those to set
our rates.
