devlink: add device information API
ethtool -i has served us well for a long time, but its showing
its limitations more and more. The device information should
also be reported per device not per-netdev.
Lay foundation for a simple devlink-based way of reading device
info. Add driver name and device serial number as initial pieces
of information exposed via this new API.
v3:
- rename helpers (Jiri);
- rename driver name attr (Jiri);
- remove double spacing in commit message (Jiri).
RFC v2:
- wrap the skb into an opaque structure (Jiri);
- allow the serial number of be any length (Jiri & Andrew);
- add driver name (Jonathan).
