This needs more thinking :)
There may be a need to identify ports, and a separate need to identify
displays connected to them.
Yet we want an API that makes sense and is not too confusing to use.
I think we should just expose Displays as device nodes instead of inside
the accelerant.
This is already done by the display_adapter driver using the ACPI nodes[1].
We need to combine info from several sources in a general way.
For instance ACPI has these:
* firmware
* brightness
* Post (default boot display)
* EDID info
* display cycling
It would make our device tree a bit more matching the physical world as
well.
