[ARM] Orion: export red SATA lights on TS-409, fix SATA presence/activity 

Export the four red SATA LEDs on the QNAP TS-409 that are connected
through gpio.  Since the boot loader apparently sets the SATA LEDs 2-4
to red and the SATA LED can only be red or green (but not both),
exporting the red SATA LEDs (which automatically turns them off upon
boot) makes the green SATA presence/activity indication visible.
