i7core_edac: change the mem allocation scheme to make Documentation/kobject.txt happy
Kernel kobjects have rigid rules: each container object should be dynamically allocated, and can't be allocated into a single kmalloc. EDAC never obeyed this rule: it has a single malloc function that allocates all needed data into a single kzalloc. As this is not accepted anymore, change the allocation schema of the EDAC *_info structs to enforce this Kernel standard.
