Subject: [PATCH v4 3/9] iio: adc: palmas: remove adc_wakeupX_data

It does not seem to be used by anyone and later patches in this series
are made simpler by first removing this. There is now a lot of dead code
that cannot be reached, until later patches revive it. Arguably, this is
preferred over removing the code only to add it again.
