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.
