Paul Burton 64243c2a94 MIPS: Move FP usage checks into protected_{save, restore}_fp_context 
In preparation for sharing protected_{save,restore}_fp_context with
compat ABIs, move the FP usage checks into said functions. This will
both enable that code to be shared, and allow for extensions of it in
further patches to also be shared.
