In gadget mode On bcm2835 platform the host tx fifo size could be zero.
So add zero to range and avoid such nonsense errors:
dwc2 20980000.usb: 0 invalid for host_nperio_tx_fifo_size.
dwc2 20980000.usb: Setting host_nperio_tx_fifo_size to 0
dwc2 20980000.usb: 0 invalid for host_perio_tx_fifo_size.
dwc2 20980000.usb: Setting host_perio_tx_fifo_size to 0
