cacheinfo: Add function to get cacheinfo for a given CPU and cache level
Resctrl open codes a search for information about a given cache level in
a couple of places (and more are on the way).
Provide a new inline function get_cpu_cacheinfo_level() in
<linux/cacheinfo.h> to do the search and return a pointer to the
cacheinfo structure.
Add lockdep_assert_cpus_held() to enforce the comment that cpuhp lock
must be held.
Simplify the existing get_cpu_cacheinfo_id() by using this new function
to do the search.
