usb: typec: altmodes/displayport: Fix pin assignment calculation 

Commit c1e5c2f0cb ("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.
