[U-Boot] dfu broken on rk3288 dwc2_otg

[Jack Mitchell]

Hi,

Has anyone successfully used DFU on an rk3288 or dwc2_otg based board?
When trying to download a binary to the board over DFU it currently
seems to timeout and the transfer fails. I have tested the
firefly-rk3288 and also the Tinkerboard.

I have successfully used the same setup on an am335x beaglebone black on
the same U-Boot commit.
