net: mvpp2: update mvpp2 validate() implementation
Fix up the mvpp2 validate implementation to adopt the same behaviour as
mvneta:
- only allow the link modes that the specified PHY interface mode
supports with the exception of 1000base-X and 2500base-X.
- use the basex helper to deal with SFP modules that can be switched
between 1000base-X vs 2500base-X.
This gives consistent behaviour between mvneta and mvpp2.
This commit depends on "net: phylink: extend clause 45 PHY validation
workaround" so is not marked for backporting to stable kernels.
