This is not reviewable. Change the indentation and any non-functional
change in one patch and then actual changes in another.
This is also an ABI break. Though I'm not sure it's avoidable. All the
devices below the ETZPC node won't probe on existing kernel. A
simple-bus fallback for ETZPC node should solve that.
