[PATCH 2/2] drm/radeon/benchmark: allow same domains for dma copy

[alexdeucher]

From: Alex Deucher <alexander.deucher@amd.com>

Remove old comment and allow benchmarking moves within the
same memory domain for both dma and blit methods.

so as a result this is not benchmarked for these ASICS, right?
