drm/i915/dp_test: Use link caps for compliance link configs

Browse source

Use the link caps configuration mask when applying DP compliance test
link parameters during state computation.

Preserve the legacy behavior of falling back to all configurations with
the requested lane count if the requested rate and lane count pair is
not allowed.

In case no valid configuration is found fail the modeset.

v2:
- Rebase on changes using a filter object instead of a mask of
  configuration indices.
- Rebase on changes using an iteration object.
