We already use binman's 'multiple-images' feature with Chrome OS and we
want to use it for Edison. There is no real down-side.
Adjust x86 to always use multiple-images.

At present the mtrr command only support 8 MTRRs. Some SoCs have more than
that. Update the implementation to support up to 10. Read the number of
MTRRs dynamically instead.

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.

At present this function only supports FSP-M but it is also used to read
FSP-S, in which case FSP-M may be zero. Add support for showing whichever
address is present in the FSP binary.
Also change the debug() statements to log_debug() while here.

If locating the FSP header hangs for whatever reason it is useful to see

At present the MTRR registers are programmed with the list the U-Boot
builds up in the same order. In some cases this list may be out of order.
It looks better in Linux to have the registers in order, so sort them,
