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.

The Kconfig also needs to be changed. In the DRM_I915 you need to add:
select CEC_CORE if CEC_NOTIFIER
Otherwise you'll get problems if the cec driver is a module and i915 is built-in.
