This mode was disabled initially to make sure it didn't side-effect
things during early development. Now that branch is cut lets
re-enable and backport when stability is proven.

When device is plugged stays awake regardless of battery state.
When device is unplugged sleeps and power is saved.
When device is re-plugged awakes.

No functional changes; just code cleanup. On LM4 this also #ifdef's
out the 'sleep' and 'pll' commands since they're big and we don't use
them.

This change corrects charger interrupt event handling, charger enable
gpio, battery full condition, EC deep sleep mode support when AC
unplugged, and lid controlled power off.

- ec console command 'gpioget':
- SPI1_MISO should be 0 when AP off
- CHARGER_EN should be 0 after AC unplugged
- charging led should be off after AC unplugged
- when battery remaining charge < 3%, system should be powered off
without AC.
- ec console command 'sleepmask 0', turn off AP:
- deep sleep only when AC unplugged

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.

When the AP is not running and we have enough time go to STOP mode
instead of simple idle.
The EC consumption should drop from 12mW to a few mW.
This is currently not activated by default, you need to type "sleepmask
0" in the EC console to activate it.
