[PATCH 3/7] powerpc/smp: Remove get_physical_package_id

From: Srikar Dronamraju
Date: Mon Jul 27 2020 - 03:56:57 EST


Now that cpu_core_mask has been removed and topology_core_cpumask has
been updated to use cpu_cpu_mask, we no more need
get_physical_package_id.

Please note get_physical_package_id is an exported symbol. However
it was introduced recently and probably no users outside kernel.
