    x86: add rom cache variable MTRR index to tables
    
    Downstream payloads may need to take advantage of caching the
    ROM for performance reasons. Add the ability to communicate the
    variable range MTRR index to use to perform the caching enablement.
    
    An example usage implementation would be to obtain the variable MTRR
    index that covers the ROM from the coreboot tables. 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.
