Subject: [PATCH 11/21] drm/i915/sdvo: Always add a 30ms delay to make SDVO TV detection reliable

commit ba84cd1f2b5dd49bda9300c5a11373f7e14c3c66 upstream.

Commit d09c23de intended to add a 30ms delay to give the ADD time to
detect any TVs connected. However, it used the sdvo->is_tv flag to do so
which is dependent upon the previous detection result and not whether the
output supports TVs.
