Hmm, well endpoints for a single port are exclusive. So it's either a
single port and a single endpoint, or two ports and two endpoints. I
think dual link has to be single port & endpoint, as the TMDS links need
to be driven together as a single bus.

And dual-link is not really "two links". DVI dual-link means 1 clock
lane and 6 data lanes, compared to 1 clock lane and 3 data lanes for
single-link.

What about having a property for the number of data lanes?

That was already suggested by Philipp in this thread. I don't see
anything wrong with that, but I don't really see benefit either.
"dual-link" is a standard term for 6 data lanes for the DVI connector.
And the choices are 3 or 6 data lanes, nothing else.

The number of lanes of a DisplayPort connector could be 1 to 4. Also,
there's dual-mode DP which can use four lanes to drive
somewhat-like-HDMI single link TMDS signals.
