perf/x86/intel/uncore: Cache logical pkg id in uncore driver

The SNB-EP uncore driver is the only user of topology_phys_to_logical_pkg
in a performance critical path.

Change it query the logical pkg ID only once at initialization time and
then cache it in box structure. This allows to change the logical package
management without affecting the performance critical path.
