drm/i915: Iterate through the initialized DDIs to prepare their buffers
Not every DDIs is necessarily connected can be strapped off and, in the future, we'll have platforms with a different number of default DDI ports. So, let's only call intel_prepare_ddi_buffers() on DDI ports that are actually detected. We also use the opportunity to give a struct intel_digital_port to intel_prepare_ddi_buffers() as we'll need it in a following patch to query if the port supports HMDI or not. On my HSW machine this removes the initialization of a couple of (unused) DDIs.
