Due to the recent change, HDA controller driver for Intel PCH tries to bind i915 audio component always at the probe time no matter whether HDMI/DP codec is found. This is, however, superflulous for old chipsets (e.g. on IVB) where they don't have always the HDMI/DP codecs but often have only a discrete GPU instead. For the newer chipsets, we need already the i915 binding from the beginning due to power well control. Meanwhile, for older chipsets where we don't need power well, we don't need the i915 binding at the controller level. This patch removes again the i915 binding in the HDA controller driver for old Intel PCHs, but adds the binding in HDMI/DP codec driver instead. This allows still the use of the direct notification from the graphics driver while we can avoid the unnecessary load of i915 driver for machines only with another GPU.
