drm/i915/dp: Cache EDID for a detection cycle
As we may query the edid multiple times following a detect, record the
EDID found during output discovery and reuse it. This is a separate
issue from caching the output EDID across detection cycles.
v2: Implement connector->force() callback so that edid is associated
with the connector for user overrides as well (Ville)
