[PATCH v3 01/10] x86/Kconfig: Geode CPU has cmpxchg8b

From: Arnd Bergmann <arnd@arndb.de>

An older cleanup of mine inadvertently removed geode-gx1 and geode-lx
from the list of CPUs that are known to support a working cmpxchg8b.

Fixes: 88a2b4edda3d ("x86/Kconfig: Rework CONFIG_X86_PAE dependency")
