[U-Boot] Starting u-boot in USB otg mode

It got compiled. But the u-boot-sunxi-with-spl.bin still generate HOST
controller rather than Peripheral USB.
I can't see it in lsusb.

Here is the u-boot console:

=> usb stop
stopping USB..
=> usb tree
USB is stopped. Please issue 'usb start' first.
=> usb start
