drm/amd/display: Remove reliance on pipe indexing
[Why]
In certain instances, there was a reliance on pipe indexing being accurate. However, this
assumption fails with harvesting of pipes 1 or 2, which can occur in production B6 parts.
HW hang would occur as a result.
[How]
Use hubp index for mpcc, and do mpc_init for all theoretical pipes (including disabled ones).
