MIPS: Fix MSA assembly warnings
Building an MSA capable kernel with a toolchain that supports MSA
produces warnings such as this:
arch/mips/kernel/r4k_fpu.S:229: Warning: the `msa' extension requires 64-bit FPRs
This is due to ".set msa" without ".set fp=64" in the non doubleword MSA
load/store macros, since MSA requires the 64-bit FPU registers (FR=1).
Add the missing fp=64 in these macros to silence the warnings.
