drm/i915: hdmi: add CEC notifier to intel_hdmi
This patchs adds the cec_notifier feature to the intel_hdmi part of the i915 DRM driver. It uses the HDMI DRM connector name to differentiate between each HDMI ports. The changes will allow the i915 HDMI code to notify EDID and HPD changes to an eventual CEC adapter.
