    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.
