Merge branch 'Devlink-regions-for-SJA1105-DSA-driver'

Vladimir Oltean says:

====================
Devlink regions for SJA1105 DSA driver

This series exposes the SJA1105 static config as a devlink region. This
can be used for debugging, for example with the sja1105_dump user space
program that I have derived from Andrew Lunn's mv88e6xxx_dump:

https://github.com/vladimiroltean/mv88e6xxx_dump/tree/sja1105

Changes in v2:
- Tear down devlink params on initialization failure.
- Add driver identification through devlink.
