Sandbox supports block devices which can access files on the host machine. At present there is no uclass for this. The devices are attached to the root devic. The block-device type is therefore set to UCLASS_ROOT which is confusing.
Block devices should be attached to a 'media' device instead, something which handles access to the actual media and provides the block driver for the block device. Create a new uclass to handle this. It supports two operations, to attach and detach a file on the host machine. For now this is not fully plumbed in.
