This is the first set of measures taken so that more drivers can be
transitioned towards phylink on shared (CPU and DSA) ports some time in
the future. It consists of:

- introducing warnings for drivers that currently skip phylink due to
  incomplete DT descriptions.
- introducing warning for drivers that currently skip phylink due to
  using platform data (search for struct dsa_chip_data).
- closing the possibility for new(ish) drivers to skip phylink, by
  validating their DT descriptions.
- making the code paths used by shared ports more evident.
- preparing the code paths used by shared ports for further work to fake
  a link description where that is possible.

More details in patch 4/4. Patches 2 and 3 are DSA cleanups, and patch 1
is a dependency for patch 4.
