Aaron Durbin a09760eb45 libpayload: add x86 ROM variable MTRR support 
On x86, coreboot may allocate a variable range MTRR for enabling caching
of the system ROM. Add the ability to parse this structure and add the
result to the sysinfo structure.

An example usage implementation would be to obtain the variable MTRR
index that covers the ROM from the sysinfo structure. Then one would
disable caching and change the MTRR type from uncacheable to
write-protect and enable caching. The opposite sequence is required
to tearn down the caching.
