[PATCH 06/17] drm/cirrus: Integrate connector into pipeline code

[Thomas Zimmermann]

Integrate the connector with the rest of the pipeline setup code.
Move some helpers within the file and adapt naming slightly. No
functional changes.

Done in preparation of converting cirrus to regular atomic helpers.
