m68k: selection of GENERIC_ATOMIC64 is not MMU specific
The selection of the CONFIG_GENERIC_ATOMIC64 option is not specific to the MMU being present and enabled. It is a property of certain CPU families. So select it based on those CPU types being selected. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
