Thomas Prescher b6032bc492 arch: fix extended topology enumeration subleafs ...

When booting a Linux guest in SMP configuration, on sapphire rapids
and granite rapids the following kernel warning can be observed:

[Firmware Bug]: CPUID leaf 0x1f subleaf 1 APIC ID mismatch 1 != 0
[Firmware Bug]: CPUID leaf 0x1f subleaf 2 APIC ID mismatch 1 != 0

The reason is that we announce the presence of the extended topology
leaf, but fail to announce the x2apic ID in EDX for each subleaf.
