Merge branch 'add-devlink-and-devlink-health-reporters-to'

George Cherian says:

====================
Add devlink and devlink health reporters to octeontx2

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.

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.
