TCPMv2: Check charge port when booting
When booting into S0, take the current charge port into account when
deciding whether to power role swap. If the port has been selected from
the UI as a charge port, then refrain from swapping and continue to
charge from it.
BRANCH=None
BUG=b:179334214,b:179095748,b:178070314
TEST=on madoo, connect to magolor and select charging from magolor on
the UI. Go through suspend and shutdown iterations and confirm that
madoo continues to charge from magolor
