Merge branch 'avr32dd20-devkit' into trunk

Added support for AVR DD MCUs, particularly avr32dd20.  Also did a bunch
of refactoring for how MCU support works, cleaned up the ADC code,
switched to consistent internal formats for voltage and temperature,
fixed the FW3X, and some other little things.

* avr32dd20-devkit: (28 commits)
  eliminated direct CCP register access from arch/attiny1616
  made the avr32dd20 flashing script more universal
  added a build target for FW3X with manually-fixed RGB aux wiring
  prevent future issues like the FW3X had
  fixed FW3X thermal regulation
  fixed incorrect temperature history for a few seconds after waking
  fsm/adc: removed dead code
  FW3X: fixed external temperature sensor
  FW3X: multiple upgrades...
  fw3x: fixed swapped red+blue, fixed battery measurements, added police color strobe
  fixed ADC on sp10-pro
  fixed ADC on attiny85 and related builds
  fixed ADC on attiny1634 and related builds
  more ADC / DAC / MCU progress...
  avr32dd20-devkit: make the defaults a bit more dev friendly (realtime voltage colors, and no simple UI by default)
  ADC voltage: battcheck 3 digits, fixed t1616, switched back to 8-bit internal volt unit
  got ADC voltage+temp working on avrdd... but broke all other builds/MCUs
  1.55V AA battery should not show as "white" voltage color, only purple
  started refactoring fsm/adc.*, but need a checkpoint before continuing
  added dac-scale.py: short script to calculate avrdd DAC+Vref values from level_calc.py ramp data
