mfd: Refactor ab8500 GPADC API, add raw access
Refactor the GPADC interface to avoid bugs in calling code:
- ab8500_gpadc_[convert|read_raw|ad_to_voltage] clarifies
each functions use case, *convert wraps *read_raw, and we
can access raw ADC values properly.
- Renamed gpadc function arguments from "input" to "channel" to
clarify use, so we don't get confused again.
