x86/topology: Add TOPO_CPU_TYPE_LOW_POWER
AMD heterogeneous parts report a third core type via CPUID Fn0x80000026
EBX[31:28] (Extended CPU Topology, Core Type):
0 - Performance
1 - Efficiency
2 - Low Power
get_topology_cpu_type() only translates the first two, so on parts that ship
low-power cores the third type falls through to TOPO_CPU_TYPE_UNKNOWN.
Add TOPO_CPU_TYPE_LOW_POWER which takes care of this new type.
