Can you manually turn the LED on, using /sys/class/led/.../brightness?
It could be we have the wrong GPIO line for the led. It would be good

They are out of tree patches. There was some discussion about SATA led
activity maybe 6 to 9 months ago. Maybe you can see why the suggested
patches got rejected. If i remember correctly, it was because they are
in the hot path.
