leds: call led_pwm_set() in leds-pwm to enforce default LED_OFF
Some PWMs are disabled by default or the default pin setting
does not match the LED_OFF state (e.g., active-low leds).
Hence, the driver may end up reporting 0 brightness, but
the leds are actually on using full brightness, because
it never enforces its default configuration.
So enforce it by calling led_pwm_set() after successfully
registering the device.
Tested on a Phytec phyFLEX i.MX6Q board based on kernel
v3.19.5.
