imx233/fuze+: rework lradc/adc code, add external temperature sensing(battery)
...
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)

imx233: remove virtual 5V channel (value doesn't make sense), fix battery conversion (need to trigger delay)

imx233: add automatic battery conversion using delay channel, make 5V a virtual channel since it has a builtin divider
