drm/i915/tv: Remember the detected TV type

Browse source 
During detect() we would probe the connection bits to determine if
there was a TV attached, and what video input type (Component, S-Video,
Composite, etc) to use. However, we promptly discarded this vital bit of
information and never propagated it to where it was used to determine
the correct modes and setup the control registers. Fix it!

This fixes a regression from 7b334fcb45.
