efi_driver: create a parent device for all EFI block devices
Up to now root has been the parent device for all block devices created via
calling ConnectController(). This does not work well together with the
implementation of bootstd.
Add a dummy parent device for all EFI block devices.
With this change EFI block devices are also accessible via commands like
'cat', 'load', and 'ls'.
