Add the description of PWM_NOFLAGS flag property.
Signed-off-by: Oleksandr Suvorov <oleksandr.suvorov@xxxxxxxxxxx>

Changes in v2:
- add the example of PWM_NOFLAGS usage;
- Use PWM_NOFLAGS instead of PWM_POLARITY_NORMAL to avoid possible
conflict with enum pwm_polarity in <linux/pwm.h>. Also, this name
reflects the sense of the original value more precisely.
