"pwms" property has the optional 3rd cell for modification flags,
i.e. the flag for inverted polarity. Multiple pwms instances in child
nodes all have to have or haven't this flags property. Now the value
"no flags" codes with the raw constant "0".

Define the PWM_NOFLAGS to use instead of the raw "0" value.

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