Add host command to control charge state v2
This replaces the obsolete and temporary (ha!) EC_CMD_CHARGE_DUMP host
command with EC_CMD_CHARGE_STATE. This is used to monitor and adjust the new
charge state implementation, including any board-specific customizations.
This command is a single catch-all command with multiple subcommands
(similar to EC_CMD_LIGHTBAR_CMD) so that we don't have to keep adding new
top-level host commands just to support incremental changes.
BUG=chrome-os-partner:23776
BRANCH=ToT
TEST=manual
From the AP, try these commands:
ectool chargestate show
ectool chargestate param
ectool chargestate param <NUM>
ectool chargestate param <NUM> <VALUE>
Watch the EC console and use its "chg" command to verify the effects of
setting various params.
Note: the Samus-specific fast-charging profile override is param 0x10000.
You can check it with the EC console "fastcharge" command.
