+ Support the NXP Layerscape qDMA engine with command queue and legacy mode.
+ Channel virtualization is supported through enqueuing of DMA jobs to,
+ or dequeuing DMA jobs from, different work queues.
+ This module can be found on NXP Layerscape SoCs.
+ The qdma driver only work on SoCs with a DPAA hardware block.
