Honeybuns: Don't propose Vconn swaps
Honeybuns doesn't require any cable information, so avoid proposing
Vconn swaps in order to reduce traffic and reduce the liklihood of
collisions with PD 2.0 partners.
BRANCH=None
BUG=b:192051705
TEST=on honeybuns, verify both ports can successfully connect and
honeybuns never proposes a Vconn swap
