[src/trunk]: src/sys/dev/pci Mac Mini WIP:
details: https://anonhg.NetBSD.org/src/rev/4ac6d0b78ba7
branches: trunk

description:
Mac Mini WIP:
- plug the external TMDS into the right CRTC when in use
- use the right output types for Mini configs
now VGA works properly ( and not just by accident ) on my Mini 2. DVI is still
garbled but at least produces output.
