Change in coreboot[master]: cbmem: rename vdat to chromeos_acpi

[Joel Kitching (Code Review)]

Hello build bot (Jenkins),

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/27888

to look at the new patch set (#3).

Change subject: cbmem: rename vdat to chromeos_acpi
......................................................................

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.
