[Intel-gfx] [PATCH v8 2/2] drm/dp: Set aux.dev to the drm_connector device, instead of drm_device.

[Rafael Antognolli]

So far, the i915 driver and some other drivers set it to the drm_device,
which doesn't allow one to know which DP a given aux channel is related
to. Changing this to be the drm_connector provides proper nesting, still
allowing one to get the drm_device from it. Some drivers already set it
to the drm_connector.

This also removes the need to add a sysfs link for the i2c device under
the connector, as it will already be there.
