usb: gadget: mtu3: Convert interrupt handling to usb_gadget_generic_ops

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.
