pd: fix contract negotiation with dynamic PDOs
When the board is using dynamic source PDOs, we need to ensure that we
are checking the incoming sink power request against the right set of
PDOs else we might reject a valid request (e.g. with high-power source,
we need to check against the 3.0A limit if we only have one port
connected).
