[PATCH] drm/amd/display: use mpcc_count to log MPC state

According to [1]:
```
DTN only logs 'pipe_count' instances of MPCC. However in some cases
there are different number of MPCC than DPP (pipe_count).
```

As DTN log still relies on pipe_count to print mpcc state, switch to
mpcc_count in all occurrences.
