Commit c1e5c2f0cb8a ("usb: typec: altmodes/displayport: correct pin assignment for UFP receptacles") fixed the pin assignment calculation to take into account whether the peripheral was a plug or a receptacle. But the "pin_assignments" sysfs logic was not updated. Address this by using the macros introduced in the aforementioned commit in the sysfs logic too.
