platform/x86/intel: power-domains: Use topology_logical_package_id() for package ID
[ Upstream commit aa28991fd5dc4c01a40caab2bd9af8c5e06f9899 ]
Currently, tpmi_get_logical_id() calls topology_physical_package_id()
to set the pkg_id of the info structure. Since some VM hosts assign non
contiguous package IDs, topology_physical_package_id() can return a
larger value than topology_max_packages(). This will result in an
invalid reference into tpmi_power_domain_mask[] as that is allocatead
based on topology_max_packages() as the maximum package ID.
