[Skiboot] [PATCH v8 00/11] Ultravisor support in skiboot

Oliver,

I took your feedback from the last post in July to move UV device tree
creation out of hdata/spira.c into hw/ultravisor.c.  I saw some device
tree creation stuff in hdata/spira.c and but I think this makes more
sense as if we don't decompress the image we don't want the device tree
node hanging around.

Thanks,
Ryan
