x86/amd_nb: Use topology info to get AMD node count
Currently, the total AMD node count is determined by searching and counting
CPU/node devices using PCI IDs.
However, AMD node information is already available through topology
CPUID/MSRs. The recent topology rework has made this info easier to access.
Replace the node counting code with a simple product of topology info.
Every node/northbridge is expected to have a 'misc' device. Clear everything
out if a 'misc' device isn't found on a node.
