CBMEM console: Fix boards with BROKEN_CAR_MIGRATE

There is no need to call cbmemc_reinit() exclusively in romstage,
that is done as part of the CAR migration of cbmem_recovery().

CBMEM console for romstage remains disabled for boards flagged with
BROKEN_CAR_MIGRATE, but with this change it is possible to have it for
ramstage.
