Kim, Milo bb982009d3 leds-lm3530: support pwm input mode
* add 'struct lm3530_pwm_data' in the platform data
  The pwm data is the platform specific functions which generate the pwm.
  The pwm data is only valid when brightness is pwm input mode.
  Functions should be implemented by the pwm driver.
  pwm_set_intensity() : set duty of pwm.
  pwm_get_intensity() : get current the brightness.

* brightness control by pwm
  If the control mode is pwm, then brightness is changed by the duty of
  pwm=.  So pwm platform function should be called in lm3530_brightness_set().

* do not update brightness register when pwm input mode
  In pwm input mode, brightness register is not used.
  If any value is updated in this register, then the led will be off.

* when input mode is changed, set duty of pwm to 0 if unnecessary.
