EDAC/mce_amd: Use struct cpuinfo_x86.logical_die_id for Hygon NodeId 

The cpuinfo_x86.cpu_die_id is get from CPUID or MSR in the commit
028c221ed1 ("x86/CPU/AMD: Save AMD NodeId as cpu_die_id"). But the
value may not be continuous for Hygon model 4h~6h processors.

Use cpuinfo_x86.logical_die_id will always format continuous die
(or node) IDs, because it will convert the physical die ID to logical
die ID.

So use topology_logical_die_id() instead of topology_die_id() to
decode UMC ECC errors for Hygon processors.
