i7core_edac: Add support for X5670

As reported by Vernon Mauery <vernux@us.ibm.com>, X5670 (Westmere-EP) uses a
different register for one of the uncore PCI devices. Add support for
it.

Those are the PCI ID's on this new chipset:

fe:00.0 0600: 8086:2c70 (rev 02)
fe:00.1 0600: 8086:2d81 (rev 02)
fe:02.0 0600: 8086:2d90 (rev 02)
fe:02.1 0600: 8086:2d91 (rev 02)
fe:02.2 0600: 8086:2d92 (rev 02)
fe:02.3 0600: 8086:2d93 (rev 02)
fe:02.4 0600: 8086:2d94 (rev 02)
fe:02.5 0600: 8086:2d95 (rev 02)
fe:03.0 0600: 8086:2d98 (rev 02)
fe:03.1 0600: 8086:2d99 (rev 02)
fe:03.2 0600: 8086:2d9a (rev 02)
fe:03.4 0600: 8086:2d9c (rev 02)
fe:04.0 0600: 8086:2da0 (rev 02)
fe:04.1 0600: 8086:2da1 (rev 02)
fe:04.2 0600: 8086:2da2 (rev 02)
fe:04.3 0600: 8086:2da3 (rev 02)
fe:05.0 0600: 8086:2da8 (rev 02)
fe:05.1 0600: 8086:2da9 (rev 02)
fe:05.2 0600: 8086:2daa (rev 02)
fe:05.3 0600: 8086:2dab (rev 02)
fe:06.0 0600: 8086:2db0 (rev 02)
fe:06.1 0600: 8086:2db1 (rev 02)
fe:06.2 0600: 8086:2db2 (rev 02)
fe:06.3 0600: 8086:2db3 (rev 02)
(as usual, the same PCI devices repeat at ff: bus)

The PCI device 8086:2c70 is shown as:

fe:00.0 Host bridge: Intel Corporation QuickPath Architecture Generic
Non-core Registers (rev 02)

So, for this device to be recognized, it is only a matter of adding this
new PCI ID to the driver.
