I'm not sure about these values but it seems you have already successfully them.
buildroot_openlinux_kernel_4.9_fbdev_20180706 uses the following
values (which are identical to the ones on GXL/GXM, but using the
values below I couldn't get dwc2 to work on GXL when I tried it last):
  dev_tx_fifo_size[0] = 128;
  dev_tx_fifo_size[1] = 128;
  dev_tx_fifo_size[2] = 128;
  dev_tx_fifo_size[3] = 16;
  dev_tx_fifo_size[4] = 16;

Thus I'm still giving my Reviewed-by based on the assumption that the
g-tx-fifo-size values you have are working (at least for you)
