mcu: Don't default serial config option to /dev/ttyS0

If the mcu config section is omitted, it leads to confusing error
messages.  Don't default the serial config option to /dev/ttyS0 to
improve the error reporting.

# Changes
20201029: The serial option in the mcu config section no longer
defaults to /dev/ttyS0. In the rare situation where /dev/ttyS0 is the
desired serial port, it must be specified explicitly.
20201020: Klipper v0.9.0 released.
20200902: The RTD resistance-to-temperature calculation for MAX31865
