i7core_edac: Probe on Xeons eariler
On the Xeon 55XX series cpus the pci deives are not exposed via acpi so
we much explicitly probe them to make the usable as a Linux PCI device.
This moves the detection of this state to before pci_register_driver is
called. Its present position was not working on my systems, the driver
would complain about not finding a specific device.
This patch allows the driver to load on my systems.
