x86/topology: Define x86's arch_update_cpu_topology
The scheduler calls arch_update_cpu_topology() to check whether the
scheduler domains have to be rebuilt.
So far x86 has no requirement for this, but the upcoming ITMT support
makes this necessary.
Request the rebuild when the x86 internal update flag is set.
