pd: allow policy layer to ask for PR/DR_swap on new contract
Allow policy layer to request a PR or DR swap upon formation of
a power contract. Zinger always asks for a data swap so it can
be a UFP, and Samus asks for a data swap only if it is a UFP to
become a DFP.
BUG=chrome-os-partner:33754, chrome-os-partner:31195
BRANCH=samus
TEST=load onto samus and zinger and make sure they swap roles
upon connect with no collisions
