So I've got a board here that uses the same GPIOs for LEDs -- PA15 and 
PL10. I commited a few things last night:

 - There was a bug in sunxi_gpio that meant you could never set an output
   pin's state to 0. This is now fixed.
 - I added a simple LED framework, so GPIO LEDs from your board show up in
   sysctl.

Can you update your kernel and do 'sysctl hw.led' to see if you have the 
controls, and then see if changing the states of those sysctl knobs works?

  sunxi# sysctl hw.led
  hw.led.orangepi_green_pwr = 1
  hw.led.orangepi_red_status = 0
  sunxi# sysctl -w hw.led.orangepi_red_status=1
  hw.led.orangepi_red_status: 0 -> 1
  sunxi# sysctl hw.led
  hw.led.orangepi_green_pwr = 1
  hw.led.orangepi_red_status = 1

Cheers,
