Hm, we always have the intel gmbus controller, but at different offsets.
In any case the abstraction provided by i2c_adapter should be more than
enough I hope. In drm/i915 we always use the bit-banging i2c encoder, but
such quirks are all handled within the i2c_adapter we pass to the
low-level sdvo i/o functions.
