Karl Palsson 2092a6759d update libopencm3

This brings in the new ADC api for STM32 parts.

Update to new standardized ADC apis.
Drops pointless channel definitions, uses common names for common functions.
No functional changes.

Based on work in: https://github.com/libopencm3/libopencm3-examples/pull/130

Console on PA9 (tx only) 115200@8n1

Prints the ADC value on PA0 (adc channel 0) on the console
Echos half that ADC value out to DAC channel 2 on PA5
Prints the ADC value of PA1 (adc channel 1) to the console.

Recommended wiring:

pot or any resistor ladder to PA0
jumper from PA5 to PA1

example output: ... tick: 228: adc0= 3950, target adc1=1975, adc1=1979 tick: 229: adc0= 3949, target adc1=1974, adc1=1978 tick: 230: adc0= 3950, target adc1=1975, adc1=1979 tick: 231: adc0= 3949, target adc1=1974, adc1=1978 ...
