dmaengine: pl330: Move device specific debugfs file to its directory

Browse Source 
Under DMA framework every DMA device gets its dedicated directory
dmaengine/$device_name in debugfs to store any supplementary data
accessible from userspace. This change moves a single registered
debugfs file of each PL330 device from debugfs top directory to the
device specific directory, the file is renamed to "stats" to match
the most popular name among all DMA device debugfs files.

The S_IFREG mask is dropped as excessive for debugfs_create_file()
function.
