USB PD: Re-discover port partner when a contract was in place
When the pd_task starts up with an explicit contract previously in
place, re-check the partner's identity. This will happen automatically
when we EC reset into RO since pd_chipset_startup sets the flag, but for
a RO->RW jump the flag needs to be set again.
Additionally, exit DP modes before sysjumping, in order to not confuse
the port partner with a second enter mode when it had previously been
in that mode.
BUG=b:125552060
BRANCH=octopus
TEST=on unlocked octopus board, plugged in powered HDMI dongle from
hibernate state and confirmed display worked after RO->RW jump. Also
turned off software sync and confirmed console "sysjump" worked.
