Merge branch 'devlink-finish-conversion-to-generated-split_ops'

Jiri Pirko says:

====================
devlink: finish conversion to generated split_ops

This patchset converts the remaining genetlink commands to generated
split_ops and removes the existing small_ops arrays entirely
alongside with shared netlink attribute policy.

Patches #1-#6 are just small preparations and small fixes on multiple
              places. Note that couple of patches contain the "Fixes"
              tag but no need to put them into -net tree.
Patch #7 is a simple rename preparation
Patch #8 is the main one in this set and adds actual definitions of cmds
         in to yaml file.
Patches #9-#10 finalize the change removing bits that are no longer in
               use.
