soc/amd/stoneyridge/northbridge.c: remove unnecessary null check
Checking for NULL here doesn't help here. We *rely* on cdb_dev to exist
directly before this check. Coverity had found this:
*** CID 1376664: Null pointer dereferences (REVERSE_INULL)
/src/soc/amd/stoneyridge/northbridge.c: 666 in cpu_bus_scan()
660 * this silicon. It is an SOC and can't have >= 16 APICs, but
661 * we will start numbering at 0x10. We also know there is only
662 * on physical node (module in AMD speak).
663 */

665 lapicid_start = 0x10; /* Get this from devicetree? see comment above. */
CID 1376664: Null pointer dereferences (REVERSE_INULL)
Null-checking "cdb_dev" suggests that it may be null, but it has already been
dereferenced on all paths leading to the check.
666 enable_node = cdb_dev && cdb_dev->enabled;
667 cpu_bus = dev->link_list;
668
669 for (j = 0; j <= siblings; j++ ) {
670 apic_id = lapicid_start + j;
671 printk(BIOS_SPEW, "lapicid_start 0x%x, node 0x%x, core 0x%x, apicid=0x%x\n",
