James Hogan 466aec5f29 Revert "MIPS: Don't assume 64-bit FP registers for context switch" ...

This reverts commit 02987633df.

The basic premise of the patch was incorrect since MSA context
(including FP state) is saved using st.d which stores two consecutive
64-bit words in memory rather than a single 128-bit word. This means
that even with big endian MSA, the FP state is still in the first 64-bit
word.
