[POWERPC] bootwrapper: Make compression of the kernel image optional.
The --no-gzip option can be passed to the wrapper so that the kernel
image is included uncompressed into the zImage. This is intended for
bootloaders where the zImage itself can be compressed, or where boot time
is considered more important than kernel image size.
