drm/i915/hdmi: Read the HPD status before trying to read the EDID
They reliably cause HDMI to not be detected on some systems (like my
ivb or the bug reporters gm45). To fix up the very slow unplug issues
we might want to fire up a 2nd detect cycle a few hundred ms after
each hotplug. But for now at least make displays work again.
I somewhat suspect that this is confined to HDMI connectors, since all
the machines I have with DP+ outputs work correctly.

We need to be able to do link training for PIOR-connected ANX9805 from
the third supervisor handler (due to script ordering in the bios, can't
have the "user" call train because some settings are overwritten from
the modesetting bios scripts).
This moves link training for SOR-connected DP encoders to the second
supervisor interrupt, *before* we call the modesetting scripts (yes,
different ordering from PIOR is necessary). This is useful since we
should now be able to remove some hacks to workaround races between
the supervisor and link training paths.
