drm/i915: Fix sdvo connector get_hw_state function
The active output is only the currently selected one, which does not imply that it's actually enabled. Since we don't use the sdvo encoder side dpms support, we need to check whether the chip-side sdvo port is enabled instead. v2: Fix up Bugzilla links. v3: Simplify logic a bit (Chris).
