efi_loader: more short texts for protocols in efidebug

The `efidebug dh` command shows handles and the installed protocols. For
most of the protocols implemented by U-Boot a short text was shown. But for
some only the GUID was displayed.

Provide the missing short texts for the following protocols: HII String,
HII Database, HII Config Routing, Simple Network, PXE Base Code.
