drm/i915: simplify dvo dpms interface
All dvo drivers only support 2 dpms states, and our dvo driver even switches of the dvo port for anything else than DPMS_ON. Hence ditch this complexity and simply use bool enable. While reading through this code I've noticed that the mode_set function of ch7017 is a bit peculiar - it disable the lvds again, even though the crtc helper code should have done that ... This might be to work around an issue at driver load, we pretty much ignore the hw state when taking over. v2: Also do the conversion for the new ns2501 driver.
