reef/pyro/eve/snappy: source 3A on one port
Add a new source policy to provide 3A if there is only one port used
as a source.
Also ensure that the load switch on VBUS when sourcing power is properly
configured to limit the current to 1.5A or 3.0A depending on the case.

BRANCH=none
BUG=chrome-os-partner:56110
TEST=manual: connect the laptop to a type-C sink with Twinkie in between,
without anything else connected on the laptop, see 3A flowing when measuring
with Twinkie ('tw vbus'), plug a dangling C-to-A receptacle dongle on the other
port and see 1.5A flowing through Twinkie.
Force the input current limit on the sink to 3.0A and see the laptop cutting
VBUS.
