drm/amd/display: Add profiling tools for bandwidth validation
[Why]
We used this change to investigate the performance of bandwidth validation,
it will be useful to have if we need to investigate further.
[How]
We use performance counter tick numbers to profile performance, they live
at dc->debug.bw_val_profile (set .enable in debugger to turn on measuring).
