MIPS: Export FP functions used by lose_fpu(1) for KVM
commit 3ce465e04bfd8de9956d515d6e9587faac3375dc upstream.
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!

[james.hogan@imgtec.com: Only export when CPU_R4K_FPU=y prior to v3.16,
so as not to break the Octeon build which excludes FPU support. KVM
depends on MIPS32r2 anyway.]
