soc/intel/denverton_ns: Ensure CPU device has a valid link

This change calls `add_more_links()` in `denverton_init_cpus()` if
`dev->link_list` is NULL. This condition can occur if mainboard does
not add any APIC device in the device tree.

"A different lapic number in devicetree.cb needed for CPU with the
same SKU and steping (Intel Atom C3538)."
