drm/amd/display: Add stream overhead in BW calculations for 128b/132b
[Why]
Current BW calculations do not account for the additional padding added
for uncompressed pixel-to-symbol packing.
This results in X.Y being too low for 128b/132b SST streams in certain
scenarios. If X.Y is too low, end user can observe image corruption.
[How]
Add function to calculate stream overhead to timing BW calculation for
128b/132b SST cases.
