nyan*: enable CLAMP_INPUTS
Enable pinmux clamp function to avoid pinmux conflict. For pins which are configured to tristate enabled, the inputs to the controller will be clamped to zero. This can be used to avoid pinmux conflicts since the tristate bit is set to 1 in the power-on-reset pinmux setting. With pinmux clamp enabled, we need to configure all the input pins to tristate disabled. BUG=chrome-os-partner:27091 BRANCH=None TEST=built and booted successfully, display worked fine.
