MIPS: math-emu: Cleanup coding style.
o Only define variables in the outermost block o One empty line at most o Format comments as per CodingStyle o Update FSF address in licensing term comment o Spell FPU and MIPS in all capitals. o Remove ####-type of lines in comments. o Try to make things a bit most consistent between sp_*.c / dp_*.c files. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
