x86: hob: Try to show a name instead of a GUID
GUIDs are one of the seven evils of the computer world. They obfuscate the meaning and require people to look up long hex strings to decode it. Luckily only a miniscule fraction of the 10^38 possible GUIDs are in use. Add a way to decode the GUIDs known to U-Boot. Add a few more to the list for good measure.
