drm/i915: use the HDMI DDI buffer translations from VBT
We currently use the recommended values from BSpec, but the VBT specifies the correct value to use for the hardware we have, so use it. We also fall back to the recommended value in case we can't find the VBT. In addition, this code also provides some infrastructure to parse more information about the DDI ports. There's a lot more information we could extract and use in the future. v2: - Move some code to init_vbt_defaults. v3: - Rebase - Clarify the "DVO Port" matching code v4: - Use I915_MAX_PORTS - Change the HAS_DDI checks - Replace DRM_ERROR with DRM_DEBUG_KMS Signed-off-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
