[PATCH 3/3] PCI: dwc: Create debugfs files in DWC driver

[Shradha Todi]

Add call to initialize debugfs from DWC driver and create the RASDES
debugfs hierarchy for each platform driver. Since it can be used for
both DW HOST controller as well as DW EP controller, add it in the
common setup function.
