pd: do not glitch USB when going to S5 in debug mode
When we are going to S5 with a debug accessory plugged, we cannot
transition through the 'PD_DRP_FORCE_SINK' else we would
disable/re-enable the USB muxes triggering disconnections/glitches on
the USB debug console.
So, rework the management of the dual role toggling special case
(used to detect debug accessories) : remove the special DRP state and
re-write the conditions.

BUG=chrome-os-partner:41399
TEST=on Ryu, connect to the EC console through Suzy-Q and issue
the "apshutdown" command, then see the EC USB console is randomly
disconnected/re-connected or acting up.
