This patch adds a new function to create per-cpu devices.
This helps in:
1. reusing the device infrastructure to create any cpu related
attributes and corresponding sysfs instead of creating and
dealing with raw kobjects directly
2. retaining the legacy path(/sys/devices/system/cpu/..) to support
existing sysfs ABI
3. avoiding to create links in the bus directory pointing to the
device as there would be per-cpu instance of these devices with
the same name since dev->bus is not populated to cpu_sysbus on
purpose

Hi Greg,
Here is the alternate solution I could come up with instead of
creating cpu class. cpu_device_create is very similar to
device_create_groups_vargs w/o class support, but I could not
reuse anything else to avoid creating similar function.
Let me know your thoughts/suggestions on this.
