There's a bunch of messy DPCD tracing code in amdgpu that isn't needed
since we already support this in DRM. Plus, it's really spammy. So, just
get rid of it.

We already trace DPCD reads/writes on both MST and SST, there's no
reason to have this code here (plus, toggling these things with a
define at the top of the file isn't how we do things in the kernel).

DRM already supports tracing DPCD transactions, there's no reason for
the existence of this function. Also, it prints one byte per-line which
is way too loud. So, just remove it.
