[PATCH 1/5] drm/amdgpu: expand sdma copy_buffer interface with tmz parameter

I wonder if we really do need yet another function argument,
thus increasing the argument list, or if the "tmz" boolean
can/is already a property of the job/command/ib/etc., and
if it can indeed be had from the latter entity...?
Regards,
Luben
