linux-4.7.2: Use cdn.kernel.org and select EDAC_SBRIDGE

1.  Use faster cdn.kernel.org over www.kernel.org (14 MiB/s vs. 300 KiB/s)
2.  Enable EDAC driver for Intel Sandy Bridge, Ivy Bridge, and Haswell

    *   Select *PCI_MMCONFIG* (Support mmconfig PCI config space access)
    *   Select *EDAC_SBRIDGE* (Support for error detection and correction
        the Intel Sandy Bridge, Ivy Bridge and Haswell Integrated Memory
        Controllers.)

    `EDAC_SBRIDGE` depends on `PCI_MMCONFIG` to be selected.

Now, the EDAC driver finds the memory controllers, and the utilities can be
used as expected.
