[0/3] PWM i.MX27 fix disabled state for inverted signals

Hi,

this small series fixes the pwm disabled behaviour in case of an
inverted pwm signal. The current state is that in such a case the pwm
signal goes to 0V which means logical '1' for inverted pwm signals. IMO
this is wrong and should be fixed.

I've tested my patches on a custom imx6 board which uses the pwm as
backlight.

Comments and testers are welcome :)

Regards,
  Marco
