drivers/edac: fix edac_device init apis

Refactoring of sysfs code necessitated the refactoring of the
edac_device_alloc() and edac_device_add_device() apis, of moving the index
value to the alloc() function.  This patch alters the in tree drivers to
utilize this new api signature.

Having the index value performed later created a chicken-and-the-egg issue.
Moving it to the alloc() function allows for creating the necessary sysfs
entries with the proper index number
