devlink: Add reload stats
Add reload stats to hold the history per reload action type and limit.
For example, the number of times fw_activate has been performed on this
device since the driver module was added or if the firmware activation
was performed with or without reset.
Add devlink notification on stats update.
Expose devlink reload stats to the user through devlink dev get command.
Examples:
$ devlink dev show
pci/0000:82:00.0:
stats:
reload:
driver_reinit 2 fw_activate 1 fw_activate_no_reset 0
pci/0000:82:00.1:
stats:
reload:
driver_reinit 1 fw_activate 0 fw_activate_no_reset 0
$ devlink dev show -jp
