this small series fixes the pwm disabled behaviour in case of an

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

Comments and testers are welcome :)

  pwm: imx27: track clock enable/disable to simplify code
  pwm: imx27: move static pwmcr values into probe() function
