Add debugfs hooks for debugging the execution behavior of the DMA channel. The debugfs hooks get initialized by the probe function and uninitialized by the remove function. A stats file is created in debugfs. The stats file will show the information about each HIDMA channel as well as each asynchronous job queued and completed at a given time.
