When CONFIG_USB is not set, and CONFIG_USB_GADGET is set,
there is an issue:
ld:
drivers/usb/mtu3/mtu3_debugfs.o: in function 'ssusb_debugfs_create_root':
mtu3_debugfs.c:(.text+0xba3): undefined reference to 'usb_debug_root'
usb_debug_root is only built when CONFIG_USB is enabled, so here drop it
and use NULL instead.
