Analog-digital converter in machine.ADC

I've ported ADS1x15 Micropython lib for A9 (https://github.com/arlucio/ads1x15_A9)

As A9 has only 3 ADCs, it is pretty useful to expand ADCs number using the I2C interfaces. Meanwhile we don't port A9 ADC, it's also a good solution. Been using it without any problems.

Maybe it's a good idea to link it somewhere on the readme.

Awesome, people from the upstream might be interested putting it somewhere into drivers such that other ports will also benefit from your implementation. Publishing it via pip is another option.

I ported ADC for those two pins. Note that they are measuring up to 1V.
