m68k: only generate FPU instructions if CONFIG_FPU enabled
Most of the m68k code that supports a hardware FPU is surrounded by CONFIG_FPU. Be consistent and surround the hardware FPU instruction setup in setup_mm.c with CONFIG_FPU as well as the check for CONFIG_M68KFPU_EMU_ONLY. The existing classic m68k architectures all define CONFIG_FPU, so they see no change from this. But on ColdFire where we do not support the emulated FP code we can now compile without CONFIG_FPU being set as well. Signed-off-by: Greg Ungerer <gerg@linux-m68k.org>
