drm: kirin: Revert change to add register connect helper functions

Daniel noted[1] that commit d606dc9a ("drm: kirin: Add
register connect helper functions in drm init") was unnecessary
and incorrect, as drm_dev_register does register connectors for
us.

Thus, this patch reverts the change as suggested by Daniel.
