     powerpc/boot: Add OPAL console to epapr wrappers

     This patch adds an OPAL console backend to the powerpc boot wrapper so
     that decompression failures inside the wrapper can be reported to the
     user. This is important since it typically indicates data corruption in
     the firmware and other nasty things.

     Currently this only works when building a little endian kernel. When
     compiling a 64 bit BE kernel the wrapper is always build 32 bit to be
     compatible with some 32 bit firmwares. BE support will be added at a
     later date. Another limitation of this is that only the "raw" type of
     OPAL console is supported, however machines that provide a hvsi console
     also provide a raw console so this is not an issue in practice.

I can provide a config file if needed. My apologies if this was already 
reported.
