sb and soc: Enforce correct offset of member "chromeos" in global_nvs_t

The padding has recently been broken in commit 90ebf96df5
("soc/intel/skylake: Add GNVS variables and include SGX ASL") and fixed
again in commit af88398887 ("soc/intel/skylake: Fix broken GNVS offset
for chromeos").  Avoid this bug in the future.
