MIPS: asmmacro: Ensure 64-bit FP registers are used with MSA

This silences warnings like the following one when building with the
latest binutils:

arch/mips/kernel/genex.S: Assembler messages:
arch/mips/kernel/genex.S:438: Warning: the `msa' extension requires 64-bit FPRs

[ralf@linux-mips.org: Markos says binutils 2.25 and some 2.24 snapshots
are affected.]
