leds: sun50i-a100: Replace msleep() with usleep_range()

Replace msleep() with usleep_range() in sun50i_a100_ledc_suspend()
to address the checkpatch.pl warning. msleep() for such short delay
can lead to inaccurate sleep times. Switch to usleep_range()
provide more precise delay.

Fix the following warning from checkpatch.pl:

WARNING: msleep < 20ms can sleep for up to 20ms;
see Documentation/timers/timers-howto.rst
+		msleep(1);
