topology: Create core_cpus and die_cpus sysfs attributes
Create CPU topology sysfs attributes: "core_cpus" and "core_cpus_list"
These attributes represent all of the logical CPUs that share the
same core.
These attriutes is synonymous with the existing "thread_siblings" and
"thread_siblings_list" attribute, which will be deprecated.
Create CPU topology sysfs attributes: "die_cpus" and "die_cpus_list".
These attributes represent all of the logical CPUs that share the
same die.
