Add support for hardware statistics counters (if they are enabled) in
the AXI Ethernet driver. Unfortunately, the implementation is
complicated a bit since the hardware might only support 32-bit counters.

Changes in v2:
- Switch to a seqlock-based implementation to allow fresher updates
  (rather than always using stale counter values from the previous
  refresh).
- Take stats_lock unconditionally in __axienet_device_reset
- Fix documentation mismatch
