drm/amd/display: Add check for DET fetch latency hiding for dcn32
[WHY?]
Some configurations are constructed with very marginal DET buffers relative to
the worst possible time required to fetch a swath.
[HOW?]
Add a check to see that the DET buffer allocated for each pipe can hide the
latency for all pipes to fetch at least one swath.
