[PATCH xf86-video-amdgpu 2/3] modesetting: Create CONNECTOR_ID properties for outputs [v2]

["Michel Dänzer" <michel-otUistvHUpPR7s880joybQ@public.gmane.org>]

From: Keith Packard <keithp@keithp.com>

This lets a DRM client map between X outputs and kernel connectors.

v2:
	Change CONNECTOR_ID to enum -- Adam Jackson <ajax@nwnk.net>
