drm/amdgpu/display: create fake mst encoders ahead of time (v4)
Prevents a warning in the MST create connector case.
v2: create global fake encoders rather per connector fake encoders
to avoid running out of encoder indices.
v3: use the actual number of crtcs on the asic rather than the max
to conserve encoders.
v4: v3 plus missing hunk I forgot to git add.
Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1108
Fixes: c6385e503aeaf9 ("drm/amdgpu: drop legacy drm load and unload callbacks")
