From: Minas Harutyunyan <Minas.Harutyunyan@synopsys.com>
commit 84524d1232ecca7cf8678e851b254f05cff4040a upstream.
Creation EP's debugfs called earlier than debugfs folder for dwc3 device created. As result EP's debugfs are created in '/sys/kernel/debug' instead of '/sys/kernel/debug/usb/dwc3.1.auto'.
Moved dwc3_debugfs_init() function call before calling dwc3_core_init_mode() to allow create dwc3 debugfs parent before creating EP's debugfs's.
