The layout of GNVS has expectation for a fixed size array for chromeos_acpi_t. This allows us to reduce the exposure of <chromeos/gnvs.h>. If chromeos_acpi_t was the last entry in struct global_nvs padding at the end is also removed. If device_nvs_t exists, place a properly sized reserve for chromeos_acpi_t in the middle. Allocation from cbmem is adjusted such that it matches exactly the OperationRegion size defined inside the ASL.
