From: Pavel Rojtberg <rojtberg@xxxxxxxxx>
this code is redundand with xpad_send_led_command which does the same
thing using irq_out.
It is also misnamed as it is likely to be an irq out and not a bulk out.
Furthermore it was probably wrong from the start as setting the LEDs did
not work on my x360w controller before fixing xpad_send_led_command in
the last patch series.
