[PATCH v3 1/4] machine: Add helpers to get cores/threads per socket

[Zhao Liu]

From: Zhao Liu <zhao1.liu@intel.com>

The number of cores/threads per socket are needed for smbios, and are
also useful for other modules.

Provide the helpers to wrap the calculation of cores/threads per socket
so that we can avoid calculation errors caused by other modules miss
topology changes.
