Alec Berg 55abd0b93c lm4: Disable ADC module when not in use. ...

Changed ADC clock gating to disable the ADC module to conserve power,
and only enable it when needed. This saves about 15% of the power
consumed by the EC when the AP is running.

BUG=none
BRANCH=none
TEST=Run the ADC stress test. This runs 2000 consecutive ADC
reads of all the channels and verifies that the ADC module
successfully records the samples. Note that when running this
test make sure all other calls to read an ADC channel are
disabled because the ADC read function does not protect
against different tasks accesses.
