This reverts commitadb393bdd6. This relands commit6260bf712a. Reason for revert: The original CL did not handle some devices correctly. With the fixes: * commit36721a4(mb/google/brya: Add GPIO_IN_RW to all variants' early GPIO tables) * commit3bfe46c(mb/google/guybrush: Add GPIO EC in RW to early GPIO tables) * commit3a30cf9(mb/google/guybrush: Build chromeos.c in verstage This CL also fix the following platforms: * Change to always trusted: cyan. * Add to early GPIO table: dedede, eve, fizz, glados, hatch, octopus, poppy, reef, volteer. * Add to both Makefile and early GPIO table: zork. For mb/intel: * adlrvp: Add support for get_ec_is_trusted(). * glkrvp: Add support for get_ec_is_trusted() with always trusted. * kblrvp: Add support for get_ec_is_trusted() with always trusted. * kunimitsu: Add support for get_ec_is_trusted() and initialize it as early GPIO. * shadowmountain: Add support for get_ec_is_trusted() and initialize it as early GPIO. * tglrvp: Add support for get_ec_is_trusted() with always trusted. For qemu-q35: Add support for get_ec_is_trusted() with always trusted. We could attempt another land.
