One cannot call lradc_acquire in IRQ context. The solution is to reserve the
channel once at init. There is an additional complication on STMP3600 where
channel mapping is fixed.

The port uses the imx233 soc, it's a STMP3650 based Samsung player

The old driver didn't behave nicely because it waiting for
stability which could never arrive on some gestures. The new one
uses a fixed delay and averaging.

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.
