PCI uncore device support was added by patch 4. If using per-cpu pointer,
we have to setup the per-cpu pointer after the PCI driver's probe function
recognizes the uncore device. It means we have to first add the PCI uncore
device to a list, then call a function on all cpus to scan the list, find
the right uncore device and setup the per-cpu pointer.
