Subject: usb: dwc3: Fix debugfs creation flow

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.
