[Intel-gfx] [PATCH 07/12] drm/i915/dp: Populate connector->ddc

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Populate connector->ddc, and thus create the "ddc" symlink
in sysfs for analog DP SST connectors.

Let's also reorder intel_dp_aux_init() vs. drm_connector_init_with_ddc()
a bit to make sure the i2c aux ch is at least somewhat populated
before we pass it on, though drm_connector_init_with_ddc() does
not actually do anything with it.
