sysmobts-v2: Enable the LED code with the GPIO LED driver.

LED0 is the "RF Active"/Yellow LED on the sysmobts-v2. We are not
using the 'yellow' LED alias as one needs to provide two functions
that call __led_set on led_yellow_on and led_yellow_off. Initialize
the GPIO direction in the board routine as the status_led code will
not be used.
