mm/Kconfig: add MMU dependency for MIGRATION.

MIGRATION must depend on MMU, or allmodconfig for the nommu sh
architecture fails to build:

    CC      mm/migrate.o
  mm/migrate.c: In function 'remove_migration_pte':
  mm/migrate.c:134:3: error: implicit declaration of function 'pmd_trans_huge' [-Werror=implicit-function-declaration]
     if (pmd_trans_huge(*pmd))
     ^
  mm/migrate.c:149:2: error: implicit declaration of function 'is_swap_pte' [-Werror=implicit-function-declaration]
    if (!is_swap_pte(pte))
    ^
  ...

Also let CMA depend on MMU, or when NOMMU, if we select CMA, it will
select MIGRATION by force.
