[coreboot] [PATCH] Move CAR config from mainboard to CPU config for AMD GX2 boards.

[Nils]

Hi Warren,

I think you forgot to convert the rest of the GX2 boards. :)
(AMD Rumba, Lippert Frontrunner, OLPC btest and OLPC rev_a)

And when you are at it should ARCH_X86 and UDELAY_TSC also
be moved?

Thanks, Nils.
