Subject: [PATCH 04/12] arch_topology: Reset all cpus in reset_cpu_topology
For MIPS platform, when topology isn't probed by DeviceTree,
possible_cpu might be empty when calling init_cpu_topology,
that may result cpu_topology not fully reseted for all CPUs.
So here we can reset all cpus instead of possible cpus.
