[PATCH v2 23/27] drm/amdgpu: Iterate through DRM connectors correctly

Currently, every single piece of code in amdgpu that loops through connectors does it incorrectly and doesn't use the proper list iteration helpers, drm_connector_list_iter_begin() and drm_connector_list_iter_end(). Yeesh.

So, do that.
