powerpc/boot: Add an ePAPR compliant boot wrapper
This is a first cut at making bootwrapper code which will produce a zImage compliant with the requirements set down by ePAPR. This is a very simple bootwrapper, taking the device tree blob supplied by the ePAPR boot program and passing it on to the kernel. It builds on the earlier patch to build a relocatable ET_DYN zImage to meet the other ePAPR image requirements. For good measure we have some paranoid checks which will generate warnings if some of the ePAPR entry condition guarantees are not met.
