usb: board_usb_init and board_usb_cleanup calls in the fastboot command

Browse source 
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.
