imx233: factor adc accross targets The old code allowed each target to specify its adc targets but this proved useless since the target rely directly on imx233/lradc for input method and generic adc is mostly used for battery and debug. Remove all target specific files and provide a generic implemenation. The targets can still specify a battery temperature channel in powermgmt-target.h Change-Id: I68cf2e3e46379d174ac6d774ffb237bb15a19ae3

imx233: fix lradc/adc for stmp3600 and stmp3700 The lradc architecture of the stmp3600 is rather different: only channels 6 and 7 have configurable source and we need to take care when allocating channels so that we can actually measure the right channel! Delegate die temperature sensing to the power block on stmp3600. Change-Id: I0860eb4ea98240facc3d4a19d61684eca5f630cc

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) Change-Id: I5f9a24b9243db7d1e6bdb16b84bc891e61d0c318
