arch/x86: remove low coreboot table support
In addition to being consistent with all other architectures, all chipsets support cbmem so the low coreboot table path is stale and never taken. Also it's important to note the memory written in to that low area of memory wasn't automatically reserved unless that path was taken. To that end remove low coreboot table support for x86.
