Sean Keely 2a0c6774fb Use SDMA for small copies in VRAM. ...

For small copies cache flush latency is larger than data transfer
latency in local VRAM.  Select SDMA for small copies.

Environment key HSA_FORCE_SDMA_SIZE is added for easy adjustment
of the small copy size.  This may be removed after tuning is done.
