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.

Why the _raspberrypi3 modifier?  Wouldn't SERIAL_CONSOLE = "115200 ttyS0" do?

...because the raspi3 MACHINE just basically includes/requires the raspi2
MACHINE, and the raspi2 MACHINE includes/requires include/rpi-base.inc, and
it's in rpi-base.inc that we find the SERIAL_CONSOLE definition.

Originally I had pulled out the SERIAL_CONSOLE from rpi-base and added it to
each of the raspi MACHINES, 3 of which were the same (AMA0) and one was ttyS0.
Then, looking over the patch set, I thought it would be cleaner to just keep
everything as it was and only add the ttyS0 to the raspi3 MACHINE (which
requires the override).
