usb: typec: altmodes/displayport: Fix probe pin assign check
While checking Pin Assignments of the port and partner during probe, we
don't take into account whether the peripheral is a plug or receptacle.
This manifests itself in a mode entry failure on certain docks and
dongles with captive cables. For instance, the Startech.com Type-C to DP
dongle (Model #CDP2DP) advertises its DP VDO as 0x405. This would fail
the Pin Assignment compatibility check, despite it supporting
Pin Assignment C as a UFP.
Update the check to use the correct DP Pin Assign macros that
take the peripheral's receptacle bit into account.
Fixes: c1e5c2f0cb8a ("usb: typec: altmodes/displayport: correct pin assignment for UFP receptacles")
