drm/amdgpu/display: create fake mst encoders ahead of time (v4)

Browse source

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.
