MIPS: Export FP functions used by lose_fpu(1) for KVM
Export the _save_fp asm function used by the lose_fpu(1) macro to GPL
modules so that KVM can make use of it when it is built as a module.
This fixes the following build error when CONFIG_KVM=m due to commit
f798217dfd03 ("KVM: MIPS: Don't leak FPU/DSP to guest"):
ERROR: "_save_fp" [arch/mips/kvm/kvm.ko] undefined!
