edac: rewrite the sysfs code to use struct device

On a multi-memory controller system, the names "csrow%d" and "dimm%d"

So, we need to create a per-MC bus, in order to have its own namespace.

This happens because the bus is not being properly initialized.
Instead of putting the memory sub-devices inside the memory controller,
it is putting everything under the same directory:
$ tree /sys/bus/edac/
/sys/bus/edac/

On a multi-memory controller system, the names "csrow%d" and "dimm%d"
should be under "mc%d", and not at the main hierarchy level.
So, we need to create a per-MC bus, in order to have its own namespace.
