mn10300: fix build error of missing fpu_save()
When CONFIG_FPU is not enabled on arch/mn10300, <asm/switch_to.h> causes a build error with a call to fpu_save(): kernel/built-in.o: In function `.L410': core.c:(.sched.text+0x28a): undefined reference to `fpu_save' Fix this by including <asm/fpu.h> in <asm/switch_to.h> so that an empty static inline fpu_save() is defined.
