arm64: smp: remove cpu and numa topology information when hotplugging out CPU
We already repopulate the information on CPU hotplug-in, so we can safely
remove the CPU topology and NUMA cpumap information during CPU hotplug
out operation. This will help to provide the correct cpumask for
scheduler domains.
