Rework code to be more useful: - move battery channel init to lradc - always init lradc from system (previously from adc) - don't reserve channels for vddio, nmos or pmos - implement external temperature sensing using current source - use this for battery sensing on the Fuze+ (calibration needed) Change-Id: I5f9a24b9243db7d1e6bdb16b84bc891e61d0c318
