Clipv2/Clip+ : use CHG_IN adc channel, it seems to work better than BVDD and RTCSUP

Browse source 
They're all the same when charger is unplugged, but when it's plugged:
- BVDD is way too high
- RTCSUP oscillates between 2 values
- CHG_IN acts like RTCSUP on some models but seems to works fine on my Clip+
