missing current-speed property prevents autoconsole on pegasos

[Olaf Hering]

Pegasos2 has no current-speed property in
/pci at 80000000/isa at C/serial at i2F8. As a result, console=ttyS0,115200 is
still required unless the patch below is used.

What is the correct way to restore console detection on pegasos2?
