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.
