arch_topology: Provide a stub topology_core_has_smt() for !CONFIG_GENERIC_ARCH_TOPOLOGY
The arm_pmu driver is using topology_core_has_smt() for retrieving
the SMT implementation which depends on CONFIG_GENERIC_ARCH_TOPOLOGY.
The config is optional on arm platforms so provide a
!CONFIG_GENERIC_ARCH_TOPOLOGY stub for topology_core_has_smt().
