    cbfs: don't load x86 programs over the top of read-only media
    
    On x86 the early stages are currently execute-in-place which
    means they live in the memory-mapped spi flash. However, when
    loading romstage from verstage the romstage is
    execute-in-place so it's unnecessary to write over a read-only
    media -- not to mention writing to read-only memory is wrong
    to begin with.
    
    BUG=chrome-os-partner:44827
    BRANCH=None
    TEST=Built and booted glados. Noted reduction of 20ms when
         loading romstage.
