If per tick is set to 10ms, it will cause nxsig_usleep(1000) in the
sdio driver to sleep for 19ms, which is much longer than the
expected 1ms, resulting in very low write performance. Add option to
reduce CPU hogging by using sched_yield(), though it may also affect
write performance when the CPU is busy.
