Enable support for the AMD Queue-based DMA subsystem. The primary
mechanism to transfer data using the QDMA is for the QDMA engine to
operate on instructions (descriptors) provided by the host operating
system. Using the descriptors, the QDMA can move data in either the
Host to Card (H2C) direction or the Card to Host (C2H) direction.
