[Intel-gfx] [PATCH] drm/i915: Call encoder hot_plug hook only for hdmi

[Sonika Jindal]

If the same port is enumerated as hdmi as well as DP, this will call
hot_plug hook for DP as well which is not required here.
This splitting of edid read and detect is done only for HDMI with this
series.

v2: Avoid breaking DP hpd. Also corrected the commit message and
description accordingly. (Daniel)
