Alec Berg f52b23e964 samus_pd: when sinking power detect loss of VBUS and disconnect ...

Detect loss of VBUS when acting as PD sink and go to the disconnected
state. This allows us to renegotiate power when power supply drops
and switches to 5V.

BUG=none
BRANCH=none
TEST=On a samus, tested by running for a couple of hours, and verifying
that occasionally when zinger drops from 20V to 5V, we detect it and
go to the disconnected state. Note, this only happens a couple times
every hour.
