drm/i915: Allow DP to work w/o EDID

Allow returning "connected" or "unknown" connector status for DP branch
devices that don't have an EDID. Currently we'd claim the thing as
"disconnected" if there is no EDID.

This stuff used to broken already, I think, but it got more broken by
commit f21a21983ef1 ("drm/i915: Splitting intel_dp_detect")
