mainboard/google/kahlee: Also configure GPIO_9 in RAM stage
The general rule is to configure GPIOs used by coreboot in bootblock (using the reset table), and GPIOs used by OS in RAM stage. However, GPIO_9 will be used as both, and we need to reconfigure it to properly set up debounce, however, it is no longer possible to change bootblock, so we also configure it in RAM stage to make the new debounce configuration take affect.
