    baytrail: disable tco timer
    
    The TCO timer always starts ticking out of reset.
    However, depending on microcode loading and punit
    initialization the TCO timing out has a different
    impact on the sytem. Without loading microcode
    or initializing the punit the tco times out and
    nothing happens. However, when microcode is loaded
    a timeout will reset the system. Lastly, if the
    punit is initialized but the microcode isn't loaded
    the TCO timeout will shut down the system.
    
    To fix all the weird symptoms disable the TCO.
    
    BUG=chrome-os-partner:22858
    BRANCH=None
    TEST=Built and booted with microcode loading. Reset doesn't
         occur.
