gpu: nvgpu: cde: CDE optimizations
-Change cde_buf to use writecombined cpu mapping.
-Since reading writecombined cpu data is still slow, avoid reads in
gk20a_replace_data by checking whether a patch overwrites a whole
word.
-Remove unused distinction between src and dst buffers in cde_convert.
-Remove cde debug dump code as it causes a perf hit.
