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.
