Lee Jones 16eb9c0aae usb: mtu3: mtu3_debug: Add forward declaration of 'struct ssusb_mtk'
Without it, the build system complains that it was declared inside
the parameter list.

Fixes the following W=1 kernel build warning(s):

 In file included from drivers/usb/mtu3/mtu3_trace.c:11:
 drivers/usb/mtu3/mtu3_debug.h:29:36: warning: ‘struct ssusb_mtk’ declared inside parameter list will not be visible outside of this definition or declaration
