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.
