[RFC PATCH v2 2/6] dt-bindings: pwm: document the PWM no-flag

[Oleksandr Suvorov]

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.

 Optionally, the pwm-specifier can encode a number of flags (defined in
 <dt-bindings/pwm/pwm.h>) in a third cell:
-- PWM_POLARITY_INVERTED: invert the PWM signal polarity
+- PWM_NOFLAGS: no modification flags.
