MIPS: DSP: eleminate used_dsp.
used_dsp was meant to be used like used_math - but since the FPU context is small and lazy context switching is a stupid idea on multiprocessors this idea only got halfway implemented and those bits are were now breaking ptrace. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
