[PATCH 7/8] m68k: only generate FPU instructions of CONFIG_FPU

[Greg Ungerer <gerg@linux-m68k.org>]

Most of the m68k code that supports a hardware FPU is surrounded by
CONFIG_FPU. Except this setup code in setup_mm.c. Be consistent and
surround these hardware FPU instructions with CONFIG_FPU instead of
a check based on CONFIG_M68KFPU_EMU_ONLY.

The side effect of this is that we can now compile a kernel with no
m68k/ColdFire hardware support FPU instructions at all (if we do not
define CONFIG_FPU).
