mach-kirkwood: Add support for D-Link DNS-325

This patch adds support for the D-Link DNS-325 NAS. A kirkwood-based successor to the DNS-323.

---
The code is largely based on either other kirkwood devices or the DNS-323, so there shouldn't be anything too weird. A few points though:-

* There are still unexplored sections of the hardware, a reset button and D-link have an option to for "power-off recovery". Will continue to search the D-Link code for them, but the NAS is pretty functional without for now.

* I'm not entirely convinced by permanently stealing the SATA power GPIOs, however it seems safer than them possibly getting switched off accidentally.

* There's a high chance that the DNS-320 (a cheaper device released at the same time, with ~identical specs) could be supported by the same setup file. This is just speculation though, I've not got one of these.

* It'd be nice to expose the SATA activity LEDs as LEDs, and allow the mapping to happen in software, but there doesn't seem to be a LED trigger for that yet (unless I've missed something).

Cheers,

This patch supersedes my previous effort, adding in support for the reset button and power recovery (ensuring the NAS turns on again when power returns to the device).

* There's a high chance that the DNS-320 (a cheaper device released at the same time, with ~identical specs) could be supported by the same setup file. This is just speculation though, and haven't named it as such.
