Depending on the SDVO output_flags SDVO may have multiple connectors.
These are all initialized in intel_sdvo_output_setup(). The connector
that is initialized later will override the encoder_type that has been
set up by an earlier connector type initialization. Eventually the
one that comes last wins.
Eventually when intel_sdvo_detect() is called the active connector is
determined.
Delay encoder type initialization until the active connector is known
and set it to the type that corresponds to this connector.
v2: Remove explicit encoder type initialization to
DRM_MODE_ENCODER_NONE in the SDVO connector setup functions
as suggested by Chris Wilson <ch...@chris-wilson.co.uk>.
