Amaury Pouly f4fdf1ffe2 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.
