e5f4032866 Clean up USB external power module
Make internal APIs static, and remove board_ prefix for clarity.

Move TSU6721 calls from charger task to extpower_usb functions for
better encapsulation.

No functional changes, just moving code.  Yes, this will make
cherry-picking back from spring to TOT less convenient, but now the
code is more readable and it will make maintaining the PMU code easier
as we add boards.

When the system is turned off and then back on, we need to re-enable

19920f1f74 spring: reset TSU6721 when Toad's ID changes
When Toad's ID changes, VBUS goes low for 10ms. This, however, is not
picked up by TSU6721 and thus we need to monitor VBUS and reset TSU6721
when necessary. By resetting TSU6721, we can force it to update device
type.

6e07f94c90 spring: More stable battery LED control
This includes:
  - Discharging with AC present now recognized as battery assist mode
  - Trigger LED update every second instead of from PMU task
  - Minor breathing effect optimization
  - Control LED power and color from the same task to prevent
    simultaneous access to LED driver

9ddb7e0708 Rename tasks to HOOKS and CHIPSET
Rename tasks

TICK -> HOOKS
  The hooks task handles more than just the TICK hook now.

X86POWER -> CHIPSET
GAIAPOWER -> CHIPSET
  Kinda kludgy that the name of the task controls which chipset source gets
  included.  Change this to a CONFIG_CHIPSET_{X86,GAIA} #define to make it
  easier to support future chipsets.  Also, rename the task function to
  chipset_task() so ec.tasklist is chipset-agnostic.

No code changes, just renaming constants and functions.

(This will matter more in future CLs which handle conditions like
"external power present, but at low power so we're doing battery

e60f1ab224 Give the AP 30 sec warning before shutting down due to low battery
This allows the AP to shut down cleanly.  If it doesn't shut down in
that time period, the EC will forcibly shut it down.

BUG=chrome-os-partner:17124
BRANCH=link
TEST=manual

1. With system off,
  - battfake 2 -> EC hibernates immediately

2. With system on,
  - battfake 2 -> battery shutdown event posted to AP
  - power off system manually within 30 sec -> EC hibernates

3. With system on,
  - battfake 2 -> battery shutdown event posted to AP
  - do not power off AP
  - after 30 sec, EC shuts down AP then hibernates

4. With system on,
  - battfake 2 -> battery shutdown event posted to AP
  - after 15 sec, apply AC power
  - system does NOT shut down
  - remove AC power -> battery shutdown event posted to AP
    (because battfake 2 is still faking 2% battery left)
  - after 30 sec, EC shuts down AP then hibernates
    (check to make sure the full 30 sec elapses; the timer
     should have been restarted when AC power was removed;
     if the EC shuts down the AP immediately this is a
     failure indicating the timer is still running from
     the first shutdown event)

6971fd7a7f After shutting down AP, hibernate EC if battery is low
This preserves more battery for the real-time clock.  It also gets rid
of one battery level/state, since the EC will now shut down at the
same level (2%) as the AP.

Having the EC hibernate at the same level as the AP shuts down also
prevents the following weird scenario:

- EC powers on at 2% battery.
- EC won't power on the AP to do software sync because battery is low.
- But the charge state machine won't actually hibernate the EC until 1%.
- Between 2% and 1%, AC is inserted and system starts charging.
- But EC-RO is what's doing the charging; we should go through software sync
  before charging.

70cdf52ea1 Wait to power on system until battery state is known
This prevents the system from waking from hibernate at very low
battery, then powering on the AP to do software sync only to find that
the charge state machine shuts down the AP before software sync can
complete.

BUG=chrome-os-partner:17124
BRANCH=link
TEST=manual

On both AC and mostly-charged battery:
- With lid open, reboot EC -> on
- With lid open, reboot EC with power held down -> on
- With lid closed, reboot EC -> system boots and does EC software sync
- With system on -> battfake 2 shuts system down
  (and at that point, opening lid or pressing power does nothing)

With a hacked charge_state.c so fake_state_of_charge starts at 2:
- With lid open or closed, reboot EC -> off
- Opening lid does not turn on system
- Pressing power button does not turn on system
- Plug power back in and press power -> system turns on
