similar to: [PATCH v2 0/4] drm/dp_mst: Fix regressions from new atomic VCPI helpers

This fixes the extra issues I discovered upstream after the introduction of my rework of the atomic VCPI helpers that occur during suspend/resume. This time around, we use a slightly different but much less complicated approach for fixing said issues.

This patchset does some cleaning up of the atomic VCPI helpers for MST, and converts nouveau over to using them. I would have included amdgpu in this patch as well, but at the moment moving them over to the atomic helpers is nontrivial.

This is the series I've been working on for a while now to get all of the atomic DRM drivers in the tree to use the atomic MST helpers, and to make the atomic MST helpers actually idempotent. Turns out it's a lot more difficult to do that without also fixing how port and branch device refcounting works so that it actually makes sense, since the current upstream implementation requires a

Looks like a regression got introduced into nv50_mstc_atomic_check() that somehow didn't get found until now. If userspace changes crtc_state->active to false but leaves the CRTC enabled, we end up calling drm_dp_atomic_find_vcpi_slots() using the PBN calculated in asyh->dp.pbn. However, if the display is inactive we end up calculating a PBN of 0, which inadvertently causes us to have an
