drm/i915: Store DVO SRCDIM register offset under intel_dvo_device

Browse Source 
Store the DVO SRCDIM register offset alongside the DVO control register
offset in intel_dvo_device. This gets rid of the switch statement whose
case values are the DVO control register offsets. Such a construct would
cause problems for register type safety.
