8bd7ab6203 pd: update source/sink cap PDOs and use to get dual role capable
Update source and sink capacity tables for all PD boards. As
per spec, the first entry in both tables must be a fixed power
supply PDO. Added dual-role capable bit to fixed PDOs and added
new state variable to keep track of that information for each
port. This will be used to make decisions in charge manager and
to pass up via host commands.

BUG=chrome-os-partner:28869
BRANCH=samus
TEST=make buildall. use "pd 1 status" to check
if part partner is dual-role capable and check zinger is not,
C to A receptable adapter is not, and another samus is.

3a4f718f22 samus_pd: add dual-role port flag to power info host command
Add flag for whether or not device plugged into a given port is a
dual-role PD device. For now, the dual-role flag is always 0, but
need to add the flag to the host command now for compatibility
in the future.

BUG=chrome-os-partner:32650
BRANCH=samus
TEST=load onto samus, run ectool --name=cros_pd usbpdpower and
verify that for anything plugged in it says "dedicated charger"

498abf833c samus_pd: add host command to get type-c port power info
Get type-c port power info including power role, charger type,
and charging info. Also added host command to get number of type-c
ports.

Also adds new charging suppliers for pericom identified chargers
including DCP, CDP, SDP, proprietary, and other chargers. Priority
of these for charging is set in samus board file.

BRANCH=samus
TEST=run 'ectool --name=cros_pd usbpdpower' and verify correct
status with minimuffin, zinger, and type-C to type-A adapter.

2eb6cba5bd charge_manager: Move supplier list and priority hierarchy to board
Allow the list of charge suppliers and port selection priority to be
specified at the board level.

BUG=chrome-os-partner:32650
TEST=Manual on samus_pd. Plug + unplug PD and BC1.2 chargers, verify
that PD is always preferred and higher power port / supplier is always
selected.

b8f73a451d charge_manager: Add module for managing battery charge limits
charge_manager is intended to manage charge limits from various tasks
(typically PD charge tasks and USB / BC 1.2 charge tasks). These tasks
can update the charge limit of a port by calling charge_manager_update
(thread-safe function). If the charge limit has changed,
charge_manager_refresh will be queued as a deferred task, which will
select the "best" charge port and set the proper charge limit.

In order to use charge_manager, a board needs to do the following:

1. Declare PD_PORT_COUNT in usb_pd_config.h
2. Implement board_set_charge_limit
3. Implement board_set_active_charge_port
4. Call charge_manager_update whenever the available charge on a port changes.

BUG=chrome-os-partner:31361
TEST=Manual on samus_pd, with subsequent commit. Insert and remove
various chargers, check console to verify PD charger always has priority
and correct current limit is set based upon 'best' charger.
