dmaengine: pl08x: Create debugfs stats file under device folder

Browse Source 
If parent folder for a debug file is not set, then this file is created
right in top debugfs mountpoint directory, which is undesired. However
for every DMA controller device its dedicated folder below 'dmaengine'
is created by dma_async_device_register(), and this particular folder
is expected to store all device specific debug files.

The new name "stats" is selected as the most popular debugfs file name
found in other DMA controller device drivers, and the macro constant
for file mode is replaced by the octal value.
