northbridge/amd/amdfam10: Fix invalid NUMA table
The existing code generated an invalid NUMA table
that was rejected by Linux, leading to poor resource
allocation. This was due to system MMIO resources
being inserted into the table when the table should
only contain DRAM resources.
Do not include system MMIO resources (i.e. resources
with an index less than 0x10) in the NUMA table.
