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.
