[PATCH 05/11] usb: gadget: max3420: Convert interrupt handling to usb_gadget_generic_ops

[Marek Vasut]

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.
