    t132: Add timestamp collection support in t132
    
    Add a region TIMESTAMP to store all the timestamps starting from bootblock to
    end of romstage. At the end of romstage take all the timestamps in TIMESTAMP
    region and put it into cbmem
    
    BUG=chrome-os-partner:32973
    BRANCH=None
    TEST=Compiles successfully and cbmem -t prints all timestamps
