[PATCH v2] ARM: dts: Convert Linkstation Mini to Device Tree

The name of the file better reflects the manufacturer's device name
(LS-WSGL) than the original (lsmini), which exists in a kirkwood version
too.

Alexey, Thomas,
I need your approval to change the license, as Jason and Andrew
suggested using dual licensing. Do you agree with it?
The changes since the first version are:
* the license change;
* the more precise attribution to Alexey;
* gpio keys are now named, even if I find them not to be the good ones;
at least they fit with the old numbers and the recently submitted
LS-WSXL scheme;
* added "earlyprintk" to the command-line
I did not rename the leds to be like LS-WSXL, as they are a bit
different. I also did not take time to look at the NOR flash layout to
separate uboot from the config (that must be all there is in these
256KB).
Hope the patch is OK like that. Sorry for the long delay, I spent quite
some time on the IRQ0 fix, and did not have so much of it lately…
