pd: fix bug where sysjump could cause PD state to wedge
...
Fix bug in USB PD initialization after a sysjump. Since the CC pull
resistors weren't being initialized after a sysjump, we would sometimes
end up stuck in sink debounce state because we would have Rp applied
and our initial state of sink disconnected would think that a source
was attached. And since we continued to apply Rp, we would never make
a connection with a charger, so we would be stuck in sink debounce
until a reboot.
BUG=chrome-os-partner:35608
BRANCH=samus
TEST=load on samus and keep rebooting and sysjumping and making sure
that we don't falsely go to the sink debounce state.
