At this point in the conversion there should be no need to have logic to disable some symbol during the SPL build as all symbols should have an SPL counterpart. The main real changes done here are that we now must make proper use of CONFIG_IS_ENABLED(DM_SERIAL) rather than many of the odd tricks we developed prior to CONFIG_IS_ENABLED() being available.
