[PATCH iwl-next 0/3] idpf: add devlink info support with selftest

[Paul Greenwalt <paul.greenwalt@intel.com>]

Add initial devlink info support for idpf and a matching selftest.

Patch 1 fixes probe unwind by clearing drvdata on the error path.

Patch 2 introduces an idpf devlink instance and reports:
  - serial_number: device serial number for NIPA CI identification
  - fw.mgmt.api (running): driver-device communication protocol version

This follows a phased approach and reports stable, readily-available
information. Firmware version support will be added in future patches as it
becomes available through virtchnl.

Patch 3 adds a hardware selftest that validates basic devlink info
reporting and matches test patterns used by NIPA CI.

  idpf: clear drvdata on probe error path
  idpf: add devlink info support
  selftests: net: hw: add devlink info test
