[U-Boot] [PATCH v2 13/22] GPIO/LED: make more robust, if STATUS_LED isn't selected

[Benjamin Tietz]

From: Benjamin Tietz <benjamin at micronet24.de>

If STATUS_LED isn't selected, neither led_id_t is selected, nor STATUS_LED_ON.
The following will set led_id_t to a reasonable default and define STATUS_LED_ON for that case.
