leds: leds-pwm: Set led_classdev max_brightness
Currently the driver leds-pwm doesn't set max_brightness for the led device although it's platform data proides a maximum brightness. Instead it stores its own private driver struct. The max_brightness defaults to 255 for led device if it has not been set. As a result any leds-pwm device with a different maximum brightness will show incorrect behavior, as it is posible to either set a longer then period duty time or not be able to switch the led to full brightness.
