[0/15] Ebony support, spin 3

[David Gibson]

Third version of the Ebony support patch series.  Notable changes:
	- Clock speeds, memory size and MAC addresses are now obtained
from the hardware/firmware by the zImage and inserted into the device
tree accordingly.  i.e. these patches should now work on any Ebony,
not just one identical to mine.
	- The kernel can now restart the Ebony.
