Now that we have changed to remove all devices under the root hub in usb_stop(), and corrected the USB emulator select logic, it makes no sense to do various tests based on 'usb tree' output since the order of devices is no longer fixed. Remove these USB test cases related to 'usb tree'. For the USB remove test, ideally we should remove an emulator device node from the device tree, but this is so far not working. Change to test the 'usb stop' only. Signed-off-by: Bin Meng <bmeng.cn@gmail.com>
