It was previously only enabled for 1500us during boot, but in a way that triggered a needless round of notifications to other modules. This is cleaner. This also fixes adc_init() not initializing the task IDs to wake when interrupts come in, and removes some unneeded code from other init functions. BUG=chrome-os-partner:12472 TEST=boot system and run adc command. Should still provide reasonable data.
