Since all DW eDMA read and write channels are now installed in a framework of a single DMA engine device, move all the DW eDMA-specific debugfs nodes into a ready-to-use DMA-engine debugfs subdirectory. It's created during the DMA-device registration and can be found in the dma_device.dbg_dev_root field.
