edac: remove unneeded functions and add static accessor 



Collection of patches, merged into one, from Adrian that do the following:

1) This patch makes the following needlessly global functions static:
- edac_pci_get_log_pe()
- edac_pci_get_log_npe()
- edac_pci_get_panic_on_pe()
- edac_pci_unregister_sysfs_instance_kobj()
- edac_pci_main_kobj_setup()

2) Remove unneeded function edac_device_find()

3) Added #if 0 around function  edac_pci_find()

4) make the needlessly global edac_pci_generic_check() static

5) Removed function edac_check_mc_devices()

Doug Thompson modified Adrian's patches, to bettern represent
the direction of EDAC, and make them one patch.
