====================
devlink: Preparations for trap policers support

This patch set prepares the code for devlink-trap policer support in a
follow-up patch set [1][2]. No functional changes intended.

Policers are going to be added as attributes of packet trap groups,
which are entities used to aggregate logically related packet traps.
This will allow users, for example, to limit all the packets that
encountered an exception during routing to 10Kpps.

However, currently, device drivers register their packet trap groups
implicitly when they register their packet traps via
devlink_traps_register(). This makes it difficult to pass additional
attributes for the groups. For example, the policer bound to the group.

Therefore, this patch set converts device drivers to explicitly register
their packet trap groups. This will later allow these drivers to
register the group with additional attributes, if any.
