x86-64, NUMA: Unify emulated distance mapping
NUMA emulation needs to update node distance information. It did it
by remapping apicid to PXM mapping, even when amdtopology is being
used. There is no reason to go through such convolution. The generic
code has all the information necessary to transform the distance table
to the emulated nid space.
Implement generic distance table transformation in numa_emulation()
and drop private implementations in srat_64 and amdtopology_64. This
makes find_node_by_addr() and fake_physnodes() and related functions
unnecessary, drop them.
