Subject: [PATCH v4 03/13] usb: otg-fsm: Prevent build warning "VDBG" redefined
If usb/otg-fsm.h and usb/composite.h are included together
then it results in the build warning [1].
Prevent that by using dev_vdbg() instead.
Also get rid of MPC_LOC which doesn't seem to be used
by anyone.
[1] - warning fixed by this patch:

In file included from drivers/usb/dwc3/ep0.c:31:
