The U-Boot device trees are slightly different in a few places. Adjust them to remove most of the differences. Note that U-Boot does not support the concept of interrupts as distinct from GPIOs, so this difference remains. For sandbox, use the same keyboard file as for ARM boards and drop the host emulation bus which seems redundant. Signed-off-by: Simon Glass <sjg@chromium.org>
