Currently cpu-x86 driver is probed only for SMP. We add the same
support for UP when there is only one cpu node in the deive tree.

Changes in v3:
- Remove the call to device_probe()
- Add a comment to explain why return value is not checked
Changes in v2:
- New patch to allow cpu-x86 driver to be probed for UP
