Reports for two kinds of events are implemented, Malicious Driver
Detection (MDD) and Tx hang.

Patches 1, 2, 3: core improvements (checkpatch.pl, devlink extension)
Patch 4: rename current ice devlink/ files
Patches 5, 6, 7: ice devlink health infra + reporters

Mateusz did good job caring for this series, and hardening the code.
---
v4:
    - rebase, added patch 4 that renames curent devlink_port files

v3: - extracted devlink_fmsg_dump_skb(), and thus removed ugly copy-pasta
      present in v2 (Jakub);
    - tx hang reported is now called from service_task, to resolve calling
      it from atomic (watchog) context - patch 4

v2: patch 3 (patch 4 in v3)
    - added additional cast to long in ice_tx_hang_reporter_dump()
    - removed size_mul() in devlink_fmsg_binary_pair_put() call
