drm/i915/kunit: DP link: add baseline fixed table reference test

Browse source

Add a simple baseline test for DP link caps iteration using a fixed
standard DP configuration table. This provides a minimal validity check,
independent of more complex test setups, verifying the iterator returns
expected configurations in ascending and descending order.

v2: Unchanged.
v3: Test config iteration in lane count, rate order as well.
