drm/i915/tc: Add an enum for the TypeC pin assignment

Browse source

Add an enum for the TypeC pin assignment, which is a better way to pass
its value around than a plain integer. While at it add a description for
each pin assignment, based on the DP and DP Alt mode Standards, opting
for more details to ease any future debugging related to a given pin
assignment and the cables / sink types used.
