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

Add call to create_debugfs_files() from DWC driver to create the RASDES
debugfs structure for each platform driver. Since it can be used for both
DW HOST controller as well as DW EP controller, let's add it in the common
setup function.
