When 'usb start' is used, block devices are created for any USB flash sticks and disks, etc. When 'usb stop' is used, these block devices are currently not removed.
We don't want old block devices hanging around since they can still be visible to U-Boot. Therefore, when USB is shut down, remove and unbind all the block devices created by the USB subsystem.
Possibly we should unbind all devices which don't cause problems by being unbound. Most likely we can remove everything except USB controllers, hubs and emulators. We can consider that later.
