poppy: source 3A on one port

Browse Source 
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.

BUG=b:35577509
TEST=On soraka (rev1), connect any USB device on port 0. On port 1
     attach C-C cable to MacBook Pro. MacBook Pro charges at ~1.5A.
     Disconnect USB device on port 0, MacBook Pro charges at 3A.
TEST=On soraka (rev1), connect USB key on port 0, see it enumerating,
     plug another USB key on port 1, it enumerates too, and the device
     on port 0 does NOT disconnect/re-enumerate.
TEST=Repeat 2 tests above, but starting with port 1.
