drm/i915: Determine type before initialising connector

Browse source 
drm_connector_init sets both the connector type and the connector type_id
on the newly initialised connector.  As the connector type_id is coupled to
the connector type, the connector type cannot simply be modified on an
initialised connector.

This patch changes the order of operations on intel_sdvo_init so that the
type is determined before the connector is intialised.

This fixes a bug whereby the name card0-VGA-1 would be allocted to both a
CRT and an SDVO connector since the SDVO connector would be initialised
with type 'unknown' and hence have its type_id assigned from the wrong pool.
