TCPMv2: DPM sourcing policy - 3.0 A PD sinks
Move the sourcing policy from the charge_manager to the DPM for TCPMv2.
The first step of this policy will be to allocate 3.0 A only if a
peripheral reports requiring more than 1.5 A in their Sink Capabilities
vSafe5V operational current. For this commit, leave in some
charge_manager APIs for linking which will be re-named or removed later.
BRANCH=None
BUG=b:141690755,b:168862110
TEST=on drawcia verify:
- non-PD sink only offered 1.5 A Rp
- PD sink requiring 1.5 A or less Rp isn't offered 3.0 A
- PD sink requiring 3.0 A is offered a new 3.0 A Source Capability after
sink capability probing. Port continues to receive 3.0 A over both hard
and soft resets.
- When 2 3.0 A sinks are plugged in, only the first is offered 3.0 A.
After the first is unplugged, the second receives a 3.0 A source
capability message
