drm/i915/dvo: implement get_hw_state
Similar to the sdvo code we poke the dvo encoder whether the output is
active. Safe that dvo encoders are not standardized, so this requires
a new callback into the dvo chip driver.
Hence implement that for all 6 dvo drivers.
v2: With the newly added ns2501 we now have 6 dvo drivers instead of
just 5 ...
