SOC have internal I/O buses that can't be probed for devices. The
devices on the buses can be accessed directly without additinal
configuration required. This type of bus is represented as

The xhci driver forces DMA memory to be node aware, however, there are
several ring-related memory allocations that are not memory node aware.
This patch resolves those *alloc functions to be allocated on the proper
memory node.
