amd64_edac: add module registration routines

Also, link into Kbuild by adding Kconfig and Makefile entries.

Borislav:
- Kconfig/Makefile splitting
- use zero-sized arrays for the sysfs attrs if not enabled
- rename sysfs attrs to more conform values
- shorten CONFIG_ names
- make multiple structure members assignment vertically aligned
- fix/cleanup comments
- fix function return value patterns
- fix err labels
- fix a memleak bug caught by Ingo
- remove the NUMA dependency and use num_k8_northbrides for initializing
  a driver instance per NB.
- do not copy the pvt contents into the mci struct in
  amd64_init_2nd_stage() and save it in the mci->pvt_info void ptr
  instead.
- cleanup debug calls
- simplify amd64_setup_pci_device()

+          Recent Opterons (Family 10h and later) provide for Memory Error
+          Injection into the ECC detection circuits. The amd64_edac module
+          allows the operator/user to inject Uncorrectable and Correctable
+          errors into DRAM.
+
+          When enabled, in each of the respective memory controller directories
+          (/sys/devices/system/edac/mc/mcX), there are 3 input files:
+
+          - inject_section (0..3, 16-byte section of 64-byte cacheline),
+          - inject_word (0..8, 16-bit word of 16-byte section),
+          - inject_ecc_vector (hex ecc vector: select bits of inject word)
+
+          In addition, there are two control files, inject_read and inject_write,
+          which trigger the DRAM ECC Read and Write respectively.
