ALS: wake up ALS task when switched to RW mode
Enabling of ALS is done during resume hook.
During EC sw sync, resume hook is not called
and hence ALS task wont run.
Adding init hook to wake up the ALS task.
BUG=chrome-os-partner:48418
BRANCH=none
TEST= On Kunimitsu board, ensure sw sync is enabled.
In OS, cat /sys/bus/iio/devices/iio:devicesx/in_illuminace_input
should output valid value and not zero.
