[U-Boot] [PATCH 4/4] sunxi: Change usb-kbd interrupt polling to use an usb interrupt qeueue

Now that the ohci code supports usb interrupt qeueues we can switch (back)
to using an usb interrupt qeueue for usb-kbd interrupt polling. This
greatly reduces u-boot's latency when dealing with usb keyboards.
