stm32f0/f3: adc: extract beginnings of common v2 periph

Browse Source 
The f0, f30x and l0 have a very similar "v2" adc peripheral.
Start extracting out some of the common code, and fix the glaring bug in
adc_power_down that was affecting them both.

This is not intended to be a fully comprehensive extraction, just the first
easy steps.
