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.
