4.4-stable review patch. If anyone has any objections, please let me know.

commit 79e57dd113d307a6c74773b8aaecf5442068988a upstream.
The active_high LED of my Wistron DNMA-92 is still being recognized as active_low on 4.7.6 mainline. When I was preparing my former commit 0f9edcdd88a9 ("ath9k: Fix LED polarity for some Mini PCI AR9220 MB92 cards.") to fix that I must have somehow messed up with testing, because I tested the final version of that patch before sending it, and it was apparently working; but now it is not working on 4.7.6 mainline.
I initially added the PCI_DEVICE_SUB section for 0x0029/0x2096 above the PCI_VDEVICE section for 0x0029; but then I moved the former below the latter after seeing how 0x002A sections were sorted in the file.
This turned out to be wrong: if a generic PCI_VDEVICE entry (that has both subvendor and subdevice IDs set to PCI_ANY_ID) is put before a more specific one (PCI_DEVICE_SUB), then the generic PCI_VDEVICE entry will match first and will be used.
With this patch, 0x0029/0x2096 has finally got active_high LED on 4.7.6.
While I'm at it, let's fix 0x002A too by also moving its generic definition below its specific ones.
