Add turbo mode charger support, and tests for it.
Some chargers can run in a "turbo" mode, which lets it draw from the battery
to provide extra power to the AP in short bursts. In order for this to work
properly, the EC has to watch the current closely to make sure specific
limits are observed. It also has to recognize specific adapters, since those
limits vary depending on the rated power that the adapter can provide.
This adds the basic functionality, plus a test for it.
BUG=chrome-os-partner:20739
BRANCH=falco,peppy
TEST=manual
make BOARD=${BOARD} runtests
On Falco, you can also use the "adapter" EC command to see what's going on.
Try replacing the adapters and running that command to be sure they're
correctly identified, too:
> adapter
Adapter 65W (590mv), turbo 1, AP_throttled 0
>
We currently support 45W, 65W, and 90W adapters. Unknown adapters are
treated as 65W, but don't enable turbo mode.
