drm/i915: don't init DP or HDMI when not supported by DDI port
There's no reason to init a DP connector if the encoder just supports
HDMI: we'll just waste hundreds and hundreds of cycles trying to do DP
AUX transactions to detect if there's something there. Same goes for a
DP connector that doesn't support HDMI, but I'm not sure these
actually exist.
v2: - Use bit fields
- Remove useless identation level
- Replace DRM_ERROR with DRM_DEBUG_KMS
