I'm missing LED value setter ... so the LED toggles only because you set the 
pinmux, right ?

This fixes the gpio_led driver which needs to compare againt a
STATUS_LED_ON to enable a led.

No; it is in mailing list but you're not in cc.

No; it uses the gpio_led driver so we don't need to write the common code.
