Workaround

Async DMA linear to tiled copies are causing GPU hangs in some cases. On Cape
Verde, I can easily triggers this as described in [1]. The game Brutal Legend
also triggers similar hangs when it streams assets while gameplay.

Disabling usage of this function and using the resource_copy_region fallback
instead fixes all hangs. The attached patch does that.
