Before sysjump we need to send a soft reset to any attached devices and then disable PD communication so that we don't re-negotiate again before the sysjump. This will guarantee expected message ID is cleared for after the sysjump. This also moves executing soft reset from before sending the soft reset command to after the port partner accepts a soft reset. BUG=none BRANCH=samus TEST=test on samus. without this change, when sysjumping the PD MCU has time to re-negotiate (at least partially) before the sysjump, which causes various problems. with this change, when sysjumping, the PD MCU sends soft reset, and then does not send anything else.
