dm: MIGRATION: Add migration plan for CONFIG_DM
For many sub-systems we already require the driver model to be used. Yet
there is still a handful of boards that do not have CONFIG_DM enabled.
We should make CONFIG_DM compulsory with release v2020.01
Conversion dates for CONFIG_DM_SPL and CONFIG_DM_TPL are yet to be defined.
