Each USB download function command calls board_usb_init before registering the USB gadget and board_usb_cleanup after de-registering it. On devices currently using fasboot, musb-new is usually initialized earlier, but some other boards might need the board_usb_init call to properly initialize musb-new. This requires adding an argument (the USB controller index) to the fastboot command, as it is currently done with other USB download gadget functions.
