[U-Boot] [PATCH v2 2/2] efi_loader: device_path: show a host device in understandable form

[AKASHI Takahiro]

It would be better to give a user-friendly text to a host device
on sandbox instead of just dumping its guid.

=> host bind 0 /opt/disk/uboot_sandbox_fat.img
=> efi devices
Device           Device Path
================ ====================
0000000015c1f3a0 /VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b)
0000000015c20f00 /VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b)/Hostdev(0)
