[coreboot] [PATCH] Repair vsmsetup on GX2

[Nils]

The attached patch fixes vsmsetup for the AMD GX2 .
It was broken at least since rev 4611.
This patch is newconfig build and boot tested, it now gives a :
VSA2 VR signature verified message.

Signed-off-by: Nils Jacobs

There is at least one "little" problem with this patch:
it breaks KBUILD!
After days of searching i could not find the culprit.
Maybe someone else can fix that, or at least give me a hint?
I also attached the build log.

Thanks,Nils.
