Enable support for the AMD PTDMA controller. This controller
provides DMA capabilities to perform high bandwidth memory to
memory and IO copy operations. It performs DMA transfer through
queue-based descriptor management. This DMA controller is intended
to be used with AMD Non-Transparent Bridge devices and not for
general purpose peripheral DMA.
