vendorcode/google/chromeos: Add support for reading VPD in ACPI
This ACPI device presents an interface that allows other ACPI devices
or methods to read VPD strings. The VPDF() method is provided the
VPD partition to look in, and the name of the VPD key to find and it
will return the VPD string if it exists.
For example: VPD.VPDF ("RO", "serial_number")
BUG=b:123925776
TEST=this was tested on a sarien platform by adding ACPI code that
searches for a VPD key and returns the value it finds, and then setting
that VPD string from the OS with the Chrome OS 'vpd' utility to ensure
the ACPI method returns the correct value.
