netdevsim: rename devlink.c to dev.c to contain per-dev(asic) items
The existing devlink.c code is going to be extended to represent asic device on a bus. As this is about more than just devlink, rename the file. Do appropriate prefix renaming alongside with that. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
