Subject: [PATCH 1/5] ARM: dts: Cygnus: Fixed iProc PCIe controller properties

Rename the msi controller unit name to 'msi' to avoid collisions
with the 'msi-controller' boolean property and add the missing
'interrupt-controller' property which is necessary. We also need to
re-arrange the 'ranges' property to show the two cells as being separate
instead of combined since the DT checker is not able to differentiate
otherwise.
