drm/nouveau/device: implement a generic method to query device-specific properties
We have a need to fetch data from GPU-specific sub-devices that is not
tied to any particular engine object.
This commit provides the framework to support such queries.

This will be required to support Volta, but also allows us to remove code

drm/nouveau/disp/nv50-: simplify definition of overlay channels
Introduces a new method of defining channels available from the display,
common to all channel types, allowing for more flexibility in available
channel types/counts, and reducing the amount of boiler-plate required.
This will be required to support Volta.
