Paul Burton 762a1f4388 MIPS: disable preemption whilst initialising MSA 
Preemption must be disabled throughout the process of enabling the FPU,
enabling MSA & initialising the vector registers. Without doing so it
is possible to lose the FPU or MSA whilst initialising them causing
that initialisation to fail.
