After the commit 63edbaa48a57 ("x86/cpu/topology: Add support for the AMD 0x80000026 leaf"), the topolgy_logical_die_id() function returns the logical Core Chiplet Die (CCD) ID instead of the logical socket ID.
Since this is currently used to set MSR_AMD_CPPC_ENABLE, which needs to be set on any one of the threads of the socket, it is prudent to use topology_logical_package_id() in place of topology_logical_die_id().
