Serge Semin 6cb6e9c605 dmaengine: dw-edma: Use DMA engine device debugfs subdirectory
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.
