Implement .handle_interrupts callback as a replacement for deprecated dm_usb_gadget_handle_interrupts() function. The new callback allows for each DM capable USB gadget controller driver to define its own IRQ handling implementation without colliding with other controller drivers.
Keep the dm_usb_gadget_handle_interrupts() in this driver for non-DM case for now, until this driver gets fully converted to DM USB gadget.
