nfp: debug dump ethtool ops
- Skeleton code to perform a binary debug dump via ethtoolops
"set_dump", "get_dump_flags" and "get_dump_data", i.e. the ethtool
-W/w mechanism.
- Skeleton functions for debugdump operations provided.
- An integer "dump level" can be specified, this is stored between
ethtool invocations. Dump level 0 is still the "arm.diag" resource for
backward compatibility. Other dump levels each define a set of state
information to include in the dump, driven by a spec from FW.
