[PATCH 1/7] drm: Replace drm_connector_{un/reference} with drm_connector_{put, get}

[Thomas Zimmermann]

This patch unifies the naming of DRM functions for reference counting
of struct drm_connector. The resulting code is more aligned with the
rest of the Linux kernel interfaces.

The patch also deletes the old functions and removes them from the
Coccinelle script.
