STM32 ADC allows each channel to be sampled with a different sampling
time. There's an application note that deals with this: 'How to get
the best ADC accuracy in STM32...' It basically depends on analog input
signal electrical properties (depends on board).

Add optional 'st,min-sample-time-nsecs' property so this can be tuned
in dt.

Changes in v2:
- Use 'st,min-sample-time-nsecs' instead of 'min-sample-time'.
