chromeos / broadwell / jecht: Make save_chromeos_gpios() jecht-specific

This callback was only required for a single mainboard, and it can
easily be moved to mainboard-specific code. This patch removes it from
the global namespace and isolates it to the Jecht board. (This makes
it easier to separate vboot and chromeos code in a later patch.)
