lm4: Use a special task event for ADC conversions
This prevents other task events from continuing the ADC
conversion prematurely; potentially leading to a panic
if the conversion interrupt occurs after the ADC has
been powered down.
BUG=chrome-os-partner:26919
BRANCH=rambi
TEST=Perform ADC conversions while running a deferred function
calling itself on a 10mSec delay. Verify no panics after ~6 hours.
