drivers/edac: fix edac_mc init apis

Browse source 
Refactoring of sysfs code necessitated the refactoring of the edac_mc_alloc()
and edac_mc_add_mc() 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
