sdma read delay

Hi all,

Here's a new patch that should help with sdma issues.

This is not a replacement for https://patchwork.freedesktop.org/patch/335077/
nor https://bugs.freedesktop.org/show_bug.cgi?id=111481#c33 so ideally you
should have the 3 patches applied and the "AMD_DEBUG=nodma" workaround
disabled.

Let me know if it helps getting rid of the sdma timeout errors. Thanks!
