rockchip: rk3399: add tsadc driver
This patch configures clock for tsadc and then makes it in automatic mode to generate TSHUT when CPU temperature is higer than 120 degree Celsius. BRANCH=none BUG=chrome-os-partner:52382,chrome-os-partner:51537 TEST=Set a lower tshut threshold(45C), run coreboot and check that coreboot reboot again and again.
