Merge branch 'devlink-sanitize-variable-typed-attributes'

Jiri Pirko says:

====================
devlink: sanitize variable typed attributes

This is continuation based on first two patches of
https://lore.kernel.org/20250425214808.507732-1-saeed@kernel.org

Better to take it as a separate patchset, as the rest of the original
patchset is probably settled.

This patchset is taking care of incorrect usage of internal NLA_* values
in uapi, introduces new enum (in patch #2) that shadows NLA_* values and
makes that part of UAPI.

The last two patches removes unnecessary translations with maintaining
clear devlink param driver api.
