H A Dingenic-adc.cc91ebcc5 Wed Nov 04 13:28:43 CST 2020 Paul Cercueil <paul@crapouillou.net> iio/adc: ingenic: Fix battery VREF for JZ4770 SoC

The reference voltage for the battery is clearly marked as 1.2V in the
programming manual. With this fixed, the battery channel now returns
correct values.
