drm/i915/dp: Limit compute config joining to pipes that can actually join

Browse source

Skip joining for pipes that can't work as joiner primary pipe for the
number of pipes being joined. This limits the invalid combos early,
instead of ending up with crtc_state->joiner_pipes that would fail
during modeset. Before, crtc_state->joiner pipes could have ended up
including pipes that do not exist on the platform.
