From: Wang Qing <wangqing@vivo.com>
cluster sched_domain configured by cpu_topology[].cluster_sibling, which is set by cluster_id, cluster_id can only get from ACPI.
If the system does not enable ACPI, cluster_id is always -1, even enable SCHED_CLUSTER is invalid, this is misleading.
So we add SCHED_CLUSTER's dependency on ACPI here.
