Karl Palsson e0f377fec0 stm32f4: use new rcc_clock_setup_pll()

Batch replaced to use new api.  User code doesn't need this, but
examples should be up to date, and this avoids deprecation warnings.

Console on PA2 (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 ...
