dm: MIGRATION: Add migration plan for CONFIG_DMWIP/2019-09-19-master-imports
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.
