f2e55b9ea9 drm/nouveau/mc/tu104: initial support
Things are a bit different here on Turing, and will require further changes
yet once I've investigated them more thoroughly.

For now though, the existing GP100 code is compatible enough with one small
hack to forward on fault buffer interrupts.

3968d6920b drm/nouveau/fault: add explicit control over fault buffer interrupts
The GPU will continually fire interrupts while a fault buffer GET != PUT,
and to stop the spurious interrupts while the handler does its thing, we
were disabling the fault buffer temporarily.

This is not actually a great idea to begin with, and made worse by Volta
resetting GET/PUT when it's reactivated.  So, let's not do that.

7b0f61e91b drm/nouveau: Fix nv50_mstc->best_encoder()
As mentioned in the previous commit, we currently prevent new modesets
on recently-removed MST connectors by returning no encoder from our
->best_encoder() callback once the MST port has disappeared. This is
wrong however, because it prevents legacy modesetting users from being
able to disable CRTCs on MST connectors after the connector's respective
topology has disappeared.

So, fix this by instead by just always returning a valid encoder.

Changes since v2:
- Remove usage of atomic MST helper for now, since that got replaced
