edac: struct device: replace bus_id with dev_name(), dev_set_name()

This patch is part of a larger patch series which will remove the "char
bus_id[20]" name string from struct device.  The device name is managed in
the kobject anyway, and without any size limitation, and just needlessly
copied into "struct device".
