TCPMv2: Consult board before setting power role swap request
If a board does not want to power role swap (ex. because it is in S5),
then do not allow the DPM request for the power role swap to be set.
This is equivalent to the logic done when a PR_SWAP message is received
by the system.
BRANCH=None
BUG=b:174726240
TEST=on madoo, plug in phone and shutdown. Verify DUT does not swap to
sourcing when in S5
