[U-Boot] [UBOOT RFC PATCH 09/13] common: cmd_dfu: add an API that takes controller index for handling interrupts

[Kishon Vijay Abraham I]

Since there can be multiple USB controllers in the system,
usb_gadget_handle_interrupts should take controller index as arguments.
However such an API can only be added in board file so added
board_usb_gadget_handle_interrupts(). usb_gadget_handle_interrupts() should
be deprecated.
