CBMEM: Always select CAR_MIGRATION

Browse source 
If romstage does not make cbmem_initialize() call, linker should
optimize the code for CAR migration away.

This simplifies design of CBMEM console by a considerable amount.
As console buffer is now migrated within cbmem_initialize() call there
is no longer need for cbmemc_reinit() call made at end of romstage.
