When i915 component binding fails, it means that HDMI isn't applicable
anyway.  Although the probe with the generic HDMI parser would still
work, it's essentially useless, hence better to be left unbound.

This patch mimics the probe_id field at failing the i915 component
binding so that the generic HDMI won't be bound after that.
