[Intel-gfx] [PATCH 1/4] drm/i915: add attached connector to hdmi container

[Sonika Jindal]

From: Shashank Sharma <shashank.sharma at intel.com>

This patch adds the intel_connector initialized to intel_hdmi
display, during the init phase, just like the other encoders do.
This attachment is very useful when we need to extract the connector
pointer during the hotplug handler function
