Hi!

Extend Thomas' MADT time topology code to include SRAT based node counts to
provide a boot time based: topology_num_nodes_per_package().

This provides a best effort estimate for things like Intel CoD/SNC and AMD NPS
modes that are not otherwise enumerated.

Use this measure to address various SNC snafus.

v1: https://lkml.kernel.org/r/20260226104909.675623579@infradead.org
