tcpci: zork: battery-less AP boot needs to set DRP on unattached ports
The timing on the AP boot takes the PD stack into TOGGLE_OFF
and then immediately to TOGGLE_ON. The TOGGLE_ON is getting
lost due to being in execution past where we set the DRP and
before we go back to LOW_POWER, so it gets lost. Then when
we get back to LOW_POWER it requires a SOURCE attach to wake
up and allow the port to detect a SINK.
This CL tracks TOGGLE_x to see if we should have set DRP and
didn't and reroute back if needed so we don't lose the port.
BUG=b:152028728
BRANCH=none
TEST=verify trembyle will see unattached port after boot to AP
