Intel SandyBridge and IvyBridge (CougarPoint and PantherPoint platforms) have also the same digital port vs audio widget mapping (from port B = NID 0x05 to port D = NID 0x07) as Haswell & co. So, we can reuse the existing functions for HSW+ for these platforms without changing there, but just by re-adding the on-demand i915 binding in HDMI codec driver.
