cbmem: rename vdat to chromeos_acpi
There is a confusingly named section in cbmem called vdat. This section holds a data structure called chromeos_acpi_t, which exposes some system information to the Chrome OS userland utility crossystem. Within the chromeos_acpi_t structure, there is a member called vdat. This (currently) holds a VbSharedDataHeader. Rename the outer vdat to chromeos_acpi to make its purpose clear, and prevent the bizarreness of being able to access vdat->vdat. Additionally, disallow external references to the chromeos_acpi data structure in gnvs.c.
