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().

Fixes: 63edbaa48a57 ("x86/cpu/topology: Add support for the AMD 0x80000026 leaf")
