[U-Boot] [PATCH] efi_loader: Fix disk dp's for pre-DM/legacy devices

[Rob Clark]

This fixes an issue with OpenBSD's bootloader, and I think should also
fix a similar issue with grub2 on legacy devices.  In the legacy case
we were creating disk objects for the partitions, but not also the
parent device.
