The default of_pwm_simple_xlate() function is capable to process PWM
inverted signal polarity flag, there is no need to use exported
of_pwm_xlate_with_flags() by the drivers.

The minimal expected by of_pwm_simple_xlate() amount of pwms arguments
is changed from 3 to 2, it allows to specify less PWM arguments in the
device tree omitting secondary configuration options (in this case it
is signal polarity value). The change has side effects, only if
