Subject: [PATCHv6 net-next 0/3] Add devlink and devlink health reporters to 

Add basic devlink and devlink health reporters.
Devlink health reporters are added for NPA block.

Address Jakub's comment to add devlink support for error reporting.
https://www.spinics.net/lists/netdev/msg670712.html

For now, I have dropped the NIX block health reporters. 
This series attempts to add health reporters only for the NPA block.
As per Jakub's suggestion separate reporters per event is used and also
got rid of the counters.

Change-log:
v6
 - Address Jakub comments
 - Add reporters per event for each block.
 - Remove the Sw counter.
 - Remove the mbox version from devlink info.

v5 
 - Address Jiri's comment
 - use devlink_fmsg_arr_pair_nest_start() for NIX blocks 

v4 
 - Rebase to net-next (no logic changes).
 
v3
 - Address Saeed's comments on v2.
 - Renamed the reporter name as hw_*.
 - Call devlink_health_report() when an event is raised.
 - Added recover op too.

v2
 - Address Willem's comments on v1.
 - Fixed the sparse issues, reported by Jakub.
