[MIPS] Fix __fls for non-MIPS32/MIPS64 cpus
Only MIPS32 and MIPS64 CPUs implement clz/dclz. Therefore don't export __ilog2() for non MIPS32/MIPS64 cpus and use generic __fls bitop code for these cpus. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
