Clipv2/Clip+ : use CHG_IN adc channel, it seems to work better than BVDD and RTCSUP
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+ git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25405 a1c6a512-1295-4272-9138-f99709370657
