net/mlx5: Added devlink info callback
The callback is invoked using 'devlink dev info <pci>' command and returns
the running and pending firmware version of the HCA and the name of the
kernel driver.
If there is a pending firmware version (a new version is burned but the
HCA still runs with the previous) it is returned as the stored
firmware version. Otherwise, the running version is returned for this
field.
Output example:
$ devlink dev info pci/0000:00:06.0
pci/0000:00:06.0:
driver mlx5_core
versions:
fixed:
fw.psid MT_0000000009
running:
fw.version 16.26.0100
stored:
fw.version 16.26.0100
