Sandipan Das 57e11990f4 perf/x86/amd/uncore: Fix DF and UMC domain identification 
For uncore PMUs, a single context is shared across all CPUs in a domain.
The domain can be a CCX, like in the case of the L3 PMU, or a socket,
like in the case of DF and UMC PMUs. This information is available via
the PMU's cpumask.

For contexts shared across a socket, the domain is currently determined
from topology_die_id() which is incorrect after the introduction of
commit 63edbaa48a ("x86/cpu/topology: Add support for the AMD
0x80000026 leaf") as it now returns a CCX identifier on Zen 4 and later
systems which support CPUID leaf 0x80000026.

Use topology_logical_package_id() instead as it always returns a socket
identifier irrespective of the availability of CPUID leaf 0x80000026.
