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.
