27fed78737 qed: implement devlink dump
Gather and push out full device dump to devlink.
Device dump is the same as with `ethtool -d`, but now its generated
exactly at the moment bad thing happens.

b228cb1602 qed*: make use of devlink recovery infrastructure
Remove forcible recovery trigger and put it as a normal devlink
callback.

This allows user to enable/disable it via

    devlink health set pci/0000:03:00.0 reporter fw_fatal auto_recover false

4f5a8db27e qed: use devlink logic to report errors
Use devlink_health_report to push error indications.
We implement this in qede via callback function to make it possible
to reuse the same for other drivers sitting on top of qed in future.

9524067b9a qed: health reporter init deinit seq
Here we declare health reporter ops (empty for now)
and register these in qed probe and remove callbacks.

This way we get devlink attached to all kind of qed* PCI
device entities: networking or storage offload entity.

53916a67c3 qed: implement devlink info request
Here we return existing fw & mfw versions, we also fetch device's
serial number:

~$ sudo ~/iproute2/devlink/devlink  dev info
pci/0000:01:00.1:
  driver qed
  board.serial_number REE1915E44552
  versions:
      running:
        fw.app 8.42.2.0
      stored:
        fw.mgmt 8.52.10.0

MFW and FW are different firmwares on device.
Management is a firmware responsible for link configuration and
various control plane features. Its permanent and resides in NVM.

Running FW (or fastpath FW) is an embedded microprogram implementing
all the packet processing, offloads, etc. This FW is being loaded
on each start by the driver from FW binary blob.

The base device specific structure (qed_dev_info) was not directly
available to the base driver before. Thus, here we create and store
a private copy of this structure in qed_dev root object to
access the data.

755f982bb1 qed/qede: make devlink survive recovery
Devlink instance lifecycle was linked to qed_dev object,
that caused devlink to be recreated on each recovery.

Changing it by making higher level driver (qede) responsible for its
life. This way devlink now survives recoveries.

qede now stores devlink structure pointer as a part of its device
object, devlink private data contains a linkage structure,
qed_devlink.
