The serial console on the Raspberry Pi 3 is located at /dev/ttyS0 and not
/dev/ttyAMA0.

Pegging the core frequency at 250 avoids any fluctuations of the baud rate on
the console.

As this seems not to be unified anymore, would it make sense to remove
it from rpi-base.inc and define it in every machine conf?

Or we can use the replace method in firmware setting it to serial0.

I think it would be better to use enable_uart in config.txt for this
situation. Setting it to 1 would work on all the rpi versions with
current firmware (to be tested).

Sure, I can do that too, no problem. I'll start a new patch series for just
this one change since it is a different solution (therefore it won't be a v3
on this one).
