MIPS: math-emu: Add FP emu debugfs statistics for branches
Add FP emu debugfs counter for branches.
The new counter is displayed the same way as existing counter, and
its default path is /sys/kernel/debug/mips/fpuemustats/.
The limitation of this counter is that it counts only R6 branch
instructions BC1NEZ and BC1EQZ.
