V1.4 moves thermistor power to the always-on 5v line.
The BOGUS_TEMPERATURE_FAILSAFE_OVERRIDE is no longer
needed on this board. Add a new motherboard type to
support this feature.
The Z_MAX_PIN value was defined as no-value, but this causes
the compile to fail. Fix this by setting the Z_MAX_PIN to the
correct value (which happens to be 0 for pin PB0/DIO0/0).
