drm/i915/tv: Only poll for TV connections
As a probe for a TV connection modifies the TV_CTL register, it causes a loss of sync and a regular glitch on the output. This is highly undesirable when using the TV, so only poll for TV connections and wait for an explicit query for detecting the disconnection event.
