[coreboot] patch: utility to show numeric values of all LX registers

[ron minnich]

The Geode has MSRs. LOTS of MSRs. I get confused trying to find them.
This program was originally written for OLPC and GX, and dumps all LX
registers used in coreboot.
I have preserved the indent structure since that gives some idea of
the scope of variables.
Of particular interest are the GLD variables, since they are always
listed as offsets in the manuals,
and computing the actual number (for use in rdmsr etc.) can be really tricky.
