missing current-speed property prevents autoconsole on pegasos

missing current-speed property prevents autoconsole on pegasos

[Olaf Hering]

Pegasos2 has no current-speed property in
/pci@80000000/isa@C/serial@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?

Why not just have users who wish to use console serial port autodetection
add 3 lines to their nvramrc?

The point of autodetection is that no userinteraction is required.

I guess the serial driver does not probe the configured hardware port
speed anymore (if it ever did that).
